In nph: Planning and Analysing Survival Studies under Non-Proportional Hazards

Quick overview

The package includes functions to model survival distributions in terms of piecewise constant hazards and to simulate data from the specified distributions. Also, a function to calculate weighted log-rank tests for the comparison of two hazard functions is included. Finally, a function to calculate a test using the maximum of a set of test statistics from weighted log-rank tests is provided. This test utilizes the asymptotic multivariate normal joint distribition of the separate test statistics. The correlation is estimated from the data.
