Simulate and Plot Estimates from Cox Proportional Hazards Models R package simPH version 1.3.15 CRAN Task View: Survival (https://CRAN.R-project.org/view=Survival) Simulates and plots quantities of interest (relative hazards, first differences, and hazard ratios) for linear coefficients, multiplicative interactions, polynomials, penalised splines, and non-proportional hazards, as well as stratified survival curves from Cox Proportional Hazard models. It also simulates and plots marginal effects for multiplicative interactions. Methods described in Gandrud (2015) <doi:10.18637/jss.v065.i03>.
