A suite of diagnostic tools for two-level normal hierarchical linear models. The package offers not only traditional case-deletion diagnostics (Cook's distance, covratio, covtrace, and MDFFITS) but also provides graphics for residual analysis. Currently, case deletion is performed by iteratively refitting the model using lmer in the lme4 package, so for data sets with many groups, computation is currently slow.
