In JointAI: Joint Analysis and Imputation of Incomplete Data

First validation for rd_vcov

Description

Checks if rd_vcov is a list with elements for all grouping levels or does not specify a grouping level. If valid, this function also make sure that rd_vcov is a list per grouping level by duplicating the contents if necessary.

Usage

check_rd_vcov_list(rd_vcov, idvar)

Arguments

rd_vcov	a character string or a list describing the the random effects variance covariance structure (provided by the user)
idvar	vector with the names of all grouping variables (except "lvlone")

Value

A named list per grouping level where each elements contains information on how the random effects variance-covariance matrices on that level are structured. Per level it can be either a character string (e.g. "full") or a list specifying structures per (groups) of variable(s) (e.g. list(full = c("a", "b"), indep = "c"))
