h_mmrm_tmb_extract_cov: Extract covariance matrix from 'TMB' report and input data

In mmrm: Mixed Models for Repeated Measures

Extract covariance matrix from TMB report and input data

Description

This helper does some simple post-processing to extract covariance matrix or named list of covariance matrices if the fitting is using grouped covariance matrices.

Usage

h_mmrm_tmb_extract_cov(tmb_report, tmb_data, visit_var, is_spatial)

Arguments

tmb_report	(list) report created with TMB::MakeADFun() report function.
tmb_data	(mmrm_tmb_data) produced by h_mmrm_tmb_data().
visit_var	(character) character vector of the visit variable
is_spatial	(flag) indicator whether the covariance structure is spatial.

Value

Return a simple covariance matrix if there is no grouping, or a named list of estimated grouped covariance matrices, with its name equal to the group levels.
