Power calculator based on the test of equality of quantiles as described in the paper “Univariate and multivariate tests of equality of quantiles with right-censored data”. This calculator assumes exponential distributions for control and censoring times, with balanced groups.
You can choose the model type: Proportional hazards (exponential experimental arm), and Nonproportional hazards with late treatment effects (piecewise exponential experimental arm).
