Within-site covariance matrix Sigma_W (backward-compat wrapper)

Returns \(\Sigma_W = \Lambda_W \Lambda_W^\top + \boldsymbol\Psi_W\) and the correlation. Thin wrapper around extract_Sigma() with level = "unit_obs". Prefer the unified interface for new code.

Usage

extract_Sigma_W(fit)

Arguments

fit

A fit returned by gllvmTMB().

Value

A list with Sigma_W and R_W, or NULL.
