Stats >> Training >> Heroin data

The file heroin.txt  shows the time that heroin addicts spend in a clinic. Some addicts were still in the clinic at the end of the study and should be treated as censored observations.

Variable names:

• Clinic (1 or 2)
• Status (0 if censored, 1 if not)
• Time (number of days spent in the clinic)
• Prison (1=prison record, 0=no record)
• Dose (Methadone dosage in mg/day)
