DTR (version 1.7)

CHR.object: 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
