resolveCluster

Used by <code>vcov_sandwich</code>. For a single grouping factor
(nested design) the cluster-robust sandwich is exact; for crossed
factors no single clustering nests every random-effect block, so a
warning is issued and the sandwich is approximate.

internal

Implements the Robust Scoring Equations estimator to fit linear
mixed effects models robustly.
Robustness is achieved by modification of the scoring equations
combined with the Design Adaptive Scale approach.
