The Cochran Q test of homogeneity of effects over strata

Described in Chapter 10 "Stratified 2x2 Tables and Meta-Analysis"

Cochran_Q_test_stratified_2x2(n, link = "linear", estimatetype = "MH")

Arguments

n

the observed table (a 2x2xk matrix, where k is the number of strata)

the link function ('linear', 'log', or 'logit')

estimatetype

Mantel-Haenszel or inverse variance estimate ('MH' or 'IV')

Value

An object of the contingencytables_result class, basically a subclass of base::list(). Use the utils::str() function to see the specific elements returned.
