<div class="section-label"><span class="num">04</span> Auxiliary</div> <div class="section-title">Deeper per-threshold <em>diagnostics</em>.</div> Auxiliary fields support audits and methodology checks. They appear most often on Predict and MaxFit. A Grid composite usually does not fill this group. Each field has length T when the group is present. Example: <span class="mono">result.auxiliary.r_star</span> ## Fields | Field | Role | | --- | --- | | <span class="mono">phi</span> | Auxiliary diagnostic | | <span class="mono">lambda_sq</span> | Auxiliary diagnostic | | <span class="mono">full_var</span> | Full variance term | | <span class="mono">part_var</span> | Partial variance term | | <span class="mono">r_star</span> | Reliability-style measure | | <span class="mono">r_star_percent</span> | Percent-scaled companion to <span class="mono">r_star</span> | | <span class="mono">rho</span> | Auxiliary diagnostic | | <span class="mono">n</span> | Count related to the included sample | | <span class="mono">k</span> | Count related to variables in play | > [!note]- About these diagnostics > This page names the fields.
