Identity-Link IRT for Label-Free LLM Evaluation: Preserving Additivity in TVD-MI Scorescs.LG

Identity-link IRT improves TVD-MI scores without curvature violations.

problem Preserving additivity in TVD-MI scores for efficient LLM evaluation.
method Derives clipped-linear model from Gini entropy maximization, using identity link.
result Identity-link yields lower curvature violations (median curl 0.080-0.150) compared to probit/logit.
