Cumulative hazard ratio object

Description

This class of objects is returned by the CHR class of functions to represent a list of cumulative hazard ratio estimates and estimated standard errors for dynamic treatment regimes (DTRs). Objects of this class have methods for the functions print, summary, and plot.

Arguments

coefficients

coefficient estimate(s) for the covariate(s)

comparison
