This is an easy-to-use software for statistical power and sample size calculations. It comprises the most common tests, point estimates and confidence intervals, also for group sequential designs. Exact- and large sample approximations as well as Monte Carlo simulations are available. Any parameter may be calculated and presented as a single value, in a table or in a graph.
