software overview : survival analysis
Major innovation in computational speed

Compute power by formula rather than simulation even when accrual rates, hazard rates, and attrition rates vary from one time interval to the next.

Graph power as a function of study duration, accrual patterns, treatment effect, attrition, or any other parameter in just seconds and get a clear picture of that factor's impact in your study.

This speed is made possible by the new algorithm which bypasses the simulation, coupled with an extremely powerful interface. With any other program, the same task would require many hours of tedious computation.
