Cumulative-risk ratios to risk ratios

Description

Given a vector of cumulative-risk ratios, computes risk ratios

Usage

 CRRtoRR(CRR, DT, h = NULL)

Arguments

CRR vector of cumulative risk ratios of length m
DT vector of time increments upon which the cumulative ratios represent. For example if the hazard takes values $h_1, h_2, ..., h_m$ on the intervals $[t_1, t_2), [t_2, t_3), ..., [t_m, t_{m+1})$ then DT will be c($t_2-t_1,t_3 -t_2, ..., t_{m+1} - t_m )$
h The hazard in the reference arm, of length m

Value

The vector of risk ratios at the m time points
