Using Kaplan-Meier Survival Analysis to Test Competing Pain Relief Treatments

A pharmaceutical company is developing an anti-inflammatory medication for treating chronic arthritic pain. Of particular interest is the time it takes for the drug to take effect and how it compares to an existing medication. Shorter times to effect are considered better.

The results of a clinical trial are collected in pain_medication.sav. See the topic Sample Files for more information. Use Kaplan-Meier Survival Analysis to examine the distribution of "time to effect" and compare the effectiveness of the two treatments.
