Random data for Poly-k

Description

Random data for Poly-k for a one-way layout, with I groups.

Usage

censsamplef(n, scale.m, shape.m, scale.t, shape.t = 3, tmax)

Arguments

n a numeric vector, the numbers of individuals of length I
scale.m a numeric vector, scale parameters of the Weibull distribution for mortality
shape.m a numeric vector, shape parameters of the Weibull distribution for mortality
scale.t a numeric vector, scale parameters of the Weibull distribution for tumour induction
shape.t a numeric vector, shape parameters of the Weibull distribution for tumour induction
tmax a single numeric value, maximum time in the trial

Details

Value

A data.frame with columns

time a numeric vector of length n, the time of death of an individual
status a logical vector of length n, the tumour status at time of death (TRUE: tumour present, FALSE: no tumour present)
