perm.test.strat {AUtests}

Stratified permutation testing

Description

Calculates permutation p-values for testing independence in 2x2 case-control tables, while adjusting for categorical covariates. Inputs are given as a vector of counts in each strata defined by the covariate(s). Note that computational time can be extremely high.

Usage

perm.test.strat(m0list, m1list, r0list, r1list)

Arguments

m0list

Number of control subjects in each strata

m1list

Number of case subjects in each strata

r0list

Number of control subjects exposed in each strata

r1list

Number of case subjects exposed in each strata

Value

A permutation p-value, computed under the likelihood ratio test.

Examples

perm.test.strat(c(7000, 1000), c(11000, 1000), c(50, 30), c(70, 40))
