New features

  • Power calculation at given or adapted sample size for means, rates and survival data
  • Sample size and power calculation for survival trials with piecewise accrual time and intensity
  • Sample size and power calculation for survival trials with exponential survival time, piecewise exponential survival time and survival times that follow a Weibull distribution
  • Simulation tool for survival trials; our simulator is very fast because it was implemented with C++. Adaptive event number recalculations based on conditional power can be assessed
  • Simulation tool for designs with continuous and binary endpoints. Adaptive sample size recalculations based on conditional power can be assessed
  • Comprehensive and unified tool for performing sample size calculation for fixed sample size design
  • Enhanced plot functionalities
