Survival Noninferiority

Survival Noninferiority

Survival Noninferiority is a program to calculate either estimates of sample size or power for equivalence studies. Exponential distributions are assumed and are specified using the ratio of the hazard for the experimental treatment to the hazard for the standard treatment. The ratio of hazard rates describing equivalence is defined in the same way.
