Usage

cov_simu(sample_size = sample_size,factors=factors)

Arguments

sample_size

Total number of patients

factors

A list contains basic information about the covariate factors. Each element should have factor's name, number of levels and their frequency, as well as the hazard ratio to the reference group. Factors should be categorical data.

Examples

f1<-list(name='Region', N_level=3, prevalence=c(0.1,0.2,0.7), HR=c(1,1,1), strata=TRUE)
f2<-list(name='Gender', N_level=2, prevalence=c(0.5,0.5), HR=c(1,0.9), strata=TRUE)
factors<-list(f1,f2)
cov_simu(sample_size=300,factors=factors)
