⚠️There's a newer version (1.3.14) of this package.Take me there.

simPH (version 1.2.3)

Tools for Simulating and Plotting Quantities of Interest Estimated From Cox Proportional Hazards Models

Description

The package 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.
