(because then the variable name is used in the name of b, D, invD, ...)Replace a full with a block-diagonal variance covariance matrix
Check if a full random effects variance covariance matrix is specified
for a single variable. In that case, it is identical to a block-diagonal
matrix. Change the rd_vcov specification to blockdiag for clarity
(because then the variable name is used in the name of b, D, invD, ...)
