CRRtoRR: 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

# NOT RUN {
