Compliments.

This page has moved to my new website.

Every once in a while someone writes in with some nice things to say about my web pages. I want to record some of those comments here so I have some documentation about my web pages to help during my annual performance evaluation. These comments will not include anyone's name, email address, or other identifying information. The large gap from July 2005 to September 2006 was probably caused by problems with the mail link on my website.

June 18, 2008. I want to convey to you my sincere gratitude for your stats web pages and your "down to earth" explanations and advice regarding statistics and clinical interpretation.

April 23, 2008. Very good short article on Odds Ratio versus Relative Risk.... I am a physician so I understand the basics of stats but I would like to learn more. I like that way you can make these points easy to understand.

April 15, 2008. Hi, I am an MPH Epidemiology student and just came across your site through a google search. I just wanted to thank you, it has been very helpful!

April 14, 2008. [Name deleted] shared the link to this wonderful stats resource! Thank you!

March 29, 2008. Your explanations and examples are just wonderful and I refer my residents to your site on a regular basis.

March 24, 2008. Thanks for creating an extremely valuable website for bio-statisticians.

March 24, 2008. Thanks for this web site - I just read through the power calculations section, and it's clear, concise, and easy to understand - much appreciated!

February 15, 2008. I just wanted to reach out and say, the as a marketing person in the diagnostics industry, your statistics explanations are great. Not being a math whiz and only infrequently have to think about how to calculate specificity your tutorials are perfect. Thanks.

January 25, 2008. Sir! I appreciate the information you post on your stats site, and the way you drive for clarity in your messages. Very helpful.

January 24, 2008. I just wanted to tell you your website is my favorite for looking up stats questions.

January 8, 2008. Thanks for putting up a site that teaches Statistics in a simple manner avoiding jargon and you have done it by using simple language and solved examples. May Allah bless you.

January 6, 2008. Kudos. Yours is the best presentation I've seen on the topic. [referring to Stats: Neyman bias (December 15, 2004)]

January 4, 2008. Nice work on the likelihood stuff.

January 1, 2008. I love your stats pages. ... I appreciate your clear, concise, thorough reviews.

November 29, 2007. Hello! Good Site! Thank you!

November 29, 2007. I purchased your book, it's great.

November 21, 2007. I'm a resident in surgery at the University of Bologna, Italy. I just want to thank you so much for your "StATS": it is clear, easy accessible and your sense of humour makes everything easier.... The issue I like most is the step by step description of softwares procedures (SPSS).

October 18, 2007. Thanks for a great website. It comes up often in my google searches.

October 16, 2007. Your website has been of tremendous value - thank you for doing this!!!

October 12, 2007. I just wanted to compliment you on this web resource. I got my MPH almost 2 years ago and am now a second year medical student. Sometimes, the stats and epi can be a little bit rusty (especially for things like likelihood ratios), so it's nice to have a resource that gives real examples for a practical application of these concepts. I will definitely keep your page for future reference!

September 20, 2007. I like your titanic example!

August 29, 2007. I'm so glad I found your website because I've learnt quite a few things from it. Thank you!

August 16, 2007. Bless you. I am going to start referring people to this page [Stats: Getting IRB approval for your research]. This is the most wonderful thing I have read in days. Thank you, thank you, thank you.

August 14, 2007. You site is a great resource. I have used it many times!

August 9, 2007. I am very impressed with your website.

July 26, 2007. I just wanted to send a sincere thanks for your explanation of ROC curve interpretation (August 18, 1999). I'm supplementing logistic regression with the ROC analysis for my school psychology master's thesis, and have been unable to find a coherent, straightforward guide to interpretation for us non-statisticians! Although the ROC doesn't seem to be an obsolete analysis per se, it definitely appears to be underused and relatively unknown in the domain of psychology. I was thrilled to see that you included a step-by-step guide to interpretation, complete with excerpts from actual SPSS output. Your explanation made my week (not to mention aided the finishing touches on my results section!) Thank you again for sharing this information with discombobulated graduate students everywhere.

July 20, 2007. I also want to thank you for your “Ask Professor Mean” website; it is like having a life-line when drowning in a sea of statistics confusion.

July 18, 2007. I am a graduate student at the [location deleted] in physical anthropology and am also dancing on the outskirts of Human Genetics. My undergraduate degree is in social anthropology where the focus is on qualitative methodology, so my knowledge of statistics in genetics was inadequate. I have had to google my way through a lot of things in my research and your webpage is by far the most helpful. You make this sound so easy and simple and the examples you use are very helpful. Thank you.

July 12, 2007. Your site is brilliant and I have recommended it to my supervisors and to all the RAs in my Centre ([location deleted]). Your capacity to begin from first principles and to utilise intuitive examples is masterful. Please compile this into a text - and I promise to set it for all my future students. Thank you.

July 12, 2007. Very clear and helpful! thanks [referring to my page on odds ratios and relative risks]

July 5, 2007. This is the clearest explanation I've seen on how to read and assess a journal article---and I recently took a course on the subject! Thanks for providing this online.

June 22, 2007. The site is very useful.

June 9, 2007. I am happy to know you are maintaining such a wonderful website.

May 21, 2007. Thank you for your very clear explanation of what an ROC is. I was finally able to SMILE... ( I've read books and other sources but your explanation was the perfect one for me).

April 19, 2007. I teach statistics at [location deleted] and I just wanted to drop you a note to let you know how much I enjoy your website. Your explanations are always clear & concise.

April 12, 2007. I just wanted to thank you for such a simple explanation of standard deviation. I have to try to explain it to several of my non-math faculty members (English) teachers which I was not looking forward to doing. Your examples and definition will make it much easier. I will also send it to a friend of mine who is writing her dissertation and cannot understand what she is doing.

March 27, 2007. Thank you for a wonderful site.

February 27, 2007. There is wealth of useful information in your site. I am going to provide the link to your website to doctors at [location deleted] who are taking a course in study design. Thank you for providing well-thought out answers to many of their questions.

February 19, 2007. Hi, Just wanted to thank you for a great discussion that you posted on the internet regarding odds ratios versus risk ratios. It made tons of sense (after I read it real slowly and actually computed the example problems on the page). I'm a resident physician trying to teach myself statistics so I appreciate stuff like this. Thanks again!

February 15, 2007. I do appreciate your demonstration of how to develop a logistic regression model on the website. It's really of great help to me. Thank you very much.

January 17, 2007. I have really enjoyed your stats pages and I have learned from them!

December 14, 2006. I just found your website on Statistics and think it is great, at least for a semi-novice like myself. I have been in research for many years and am always looking for easy to understand statistical concepts for myself and others that I work with. Your website is very helpful so far. I look forward to returning when I have more time or need some help.

December 12, 2006. Thanks - your web pages are a real find.

December 12, 2006. I am a first year doctoral student in the quantitative research methodology program in [location deleted]. I teach introductory and intermediate statistics as part of my graduate assistantship. I frequently prowl the internet looking for ideas and explanations to improve my teaching, and I love your STATS pages. Admittedly, I teach to a social sciences audience, but your explanations are direct and simple.

December 11, 2006. Sir, I saw your web pages where you have tried to explain some statistical applications in medical science in a nice manner. I found them very helpful while I was going through some confusions. Thanks a lot for all what I have come to know from your tactful effort to teach statistics. Your web pages shall prove very helpful not only to a beginner like me but also to a researcher.

October 31, 2006. BTW, your website is the best.

October 17, 2006. I have found your web page discussing the value of log transformations in linear regressions very helpful.

June 8, 2005. I'm doing a stats problem set for grad school. Just wanted to say thanks for the great explanation of maximum likelihood estimation which I found via google. There were a lot of explanations on the web. Yours was the only one that helped led me on with easy examples that I understood and then once I was engaged I could make more sense of the calculus and number crunching at work. Other examples were either too simplistic or too technical for someone like myself to grapple with. thanks and best wishes.

May 25, 2005. Thanks for sharing your knowledge on the website, particularly re odds ratio/relative risk. I'm analyzing data in which I wanted to be able to say, "premenopausal women are x times more likely than men to present with a clinically significant worsening of depression". Trying to figure out how to get there was another matter. Your site helped a lot. Thanks again for making a fine resource available to all.

May 19, 2005. I found one of your "attempts" on the web today and I found the NNT lesson OUTSTANDING! It was humorous, informative and actually made sense to me. I am a basic researcher in constant pursuit of biostatisical enlightmentment and I am going back to read more of your musings. (Have you written any books?) Thanks for making this available

I can't help but put a plug in here for the book I am writing. The working title is "Statistical Evidence" and the web page describing the book and showing some of the material is at www.childrensmercy.org/stats/evidence.asp.

April 27, 2005. Thanks for the easy and to the point explanation of the t-test. I needed to understand some social research reports and I couldn't get what the bloody t(39)=8,98, p<.001 means, but I think I got it from your explanation. it's actually very easy. thank you much [name deleted] (Czech Republic)

April 26, 2005. PS: I was also pleased to see that you are working on a book. I hope it will soon come to press. I have found your explanations of statistical issues to be clear and clinically oriented.

April 23, 2005. On more than one statistics topic (power analysis, bonferroni correction, etc) I find your website to be extremely helpful and written with a clear approach that is very easy to understand...compared to various reference texts! Thanks for taking the time to provide this web-based service.

April 5, 2005. [Referring to my page on Fisher's Exact Test] Thank you for your clear, succinct explanation.

March 19, 2005. Just thought I would say thanks, I went to your website today, for a stats question, and it was very helpful, thanks. [This is from a CMH employee.]

February 23, 2005. Steve, I called you about a year ago to compliment your web page. So, when I wanted to refresh my memory about likelihood ratios, I decided to consult you again. Wow! Even nicer! You are just amazing. I am impressed not only with the clarity of your writing, but with notation that you have added about a page a day.

January 24, 2005. Just a quick note to say that I found your page on one-tailed vs. two-tailed levels of significance quite helpful. I thought I remembered from undergraduate stats that to get a 1-tailed sig from SPSS, you just divided by two. However, a memory from some years ago was not alone enough to hang my thesis data on. Cheers!

January 21, 2005. An excellent resource, had trouble choosing which gems to quote in my coursework. Thank You!

January 20, 2005. I am an instructor with [name and location deleted]. I facilitate an on-line clinical research course, and one of my students stumbled across your statistical definitions page. They've found it quite helpful...there's some positive feedback for you! In fact, I'd like to put in a link from my course site to http://www.childrensmercy.org/stats/definitions.html. Do let me know if this is problematic (and thanks for making statistics more understandable for non-statisticians.)

January 19, 2005. I really appreciated your example about the difference in partial vs. sequential ANOVA on your website.

January 9, 2005. May I say well done on a the best stat site I've been to. I'm a medical student doing a research project and I was sunk deep in a big hole trying to figure out how to do kaplan meier on spss! At my wits end and after much frustration (and a billion google searches!) I finally cracked it at 4am thanks to your website, you quite literally saved my life. Thank you so so so much!!!

January 5, 2005. I stumbled across your webpage when googling how to calculate with dates. I had done it successfully in the past but was having a brain cramp. THANK YOU. [This refers to using SPSS to calculate the number of days/months years between two date variables.]

December 8, 2004. I found http://www.cmh.edu/stats/model/linear/log.asp website very useful. It is straightforward and explicitly explains the log transformations' basic assumptions. Good page for Psychology undergraduate freshmen. Thank you very much!

November 18, 2004. I just wanted to give you some feedback on your statistics WebPages. I am a faculty member at [name deleted] School of Medicine in the Division of Neonatology. I have been looking for good resources to help the pediatric residents, and neonatology fellows gain an understanding of the more common statistical concepts. Most of the textbooks and references I have found are very dry and in many cases difficult for those new to statistics to understand. I came across your web pages, and must compliment you on their quality and utility. I particularly like the way you have set up links to common questions. I plan to suggest that our residents and fellows visit your site when the are having difficulty understanding certain statistical concepts.

October 31, 2004. I think the info on these web pages is great for some of the health professionals I work with.

September 15, 2004. I have enjoyed greatly your Web site and especially the Class #04 "Using SPSS to develop a logistic regression model".

August 23, 2004. I just wanted you to know that I find your site informative and easy to understand, thank you!

July 30, 2004. I clicked on your link after the IRBFORUM discussion on unblinding. I am most impressed! I am going to push to add your website to ours. I am sure I will be visiting it often.

July 29, 2004. I found your site very useful. [I would not normally include such a short comment, but this author writes to me from Nigeria. Isn't the Internet wonderful?]

July 8, 2004. I just happened to find your definitions while searching for statistics info for a class I'm taking. I thought I would tell you how simple and easily understood you have made these concepts for me. My professor's explanations left me hopelessly confused but I understand things much better thanks to you!

July 8, 2004. I just came across your web pages on reading a medical journal article and statistics (via HIRU) and found them very refreshing. I think your approach is very accessible--I love it. I will encourage my students to provide the feedback as they use the pages, as will I. I will also incorporate your structure (apples or oranges etc) in my slides on EBP and acknowledge your work, if that is all right with you.

June 2, 2004. Just a quick note to let you know how much I appreciate your outstanding work on this website. I'm studying for my IM boards and I needed to learn how to do a NNT computation and found your site through Yahoo. Your explanations are easily understood and for them to make sense to someone who has never taken stats is really an accomplishment. Your writing is good enough that I just started to read all your little cases about power which has been a calculation that has overwhelmed me in the past. I'm going to resume my psych residency in Sept ... and am planning now on doing some clinical research and your discussion on power reminded me of some of the things I need to have down cold in my proposal to the IRB. So, thanks and thanks again!! Great job!

April 15, 2004. Hi, I want to thank you for your website. The definitions are in plain English and very easy to understand! What a great help!
