dmbc_check_groups {dmbc}R Documentation

Auxiliary function for checking the grouping results of a fitted DMBC model.

Description

dmbc_check_groups() is an auxiliary function for checking whether the cluster membership estimates provided by the individual chains of the fitted model provided agree or not.

Usage

dmbc_check_groups(res, est = "mean")

Arguments

res

An object of class dmbc_fit_list.

est

A length-one character vector indicating the estimate type to use.

Value

A length-one logical vector, which is equal to TRUE if all simulated chains provide the same cluster membership estimates, and FALSE otherwise.
