m_resid()</a></code> returns both EB and LS higher-level residuals, otherwise known as the random effects for each group.</p></li>
<li><p><code>standardize</code> - a logical indicating if the returned residuals should be standardized. By default, <code>standardize = FALSE</code>, returning unstandardized residuals. When <code>standardize = TRUE</code>, residuals are divided by the estimated standard error. For marginal residuals, when <code>standardize = TRUE</code>, the Cholesky residuals are returned.</p
