imv - Model Comparison via the 'InterModel Vigorish' ('IMV')
Computes the 'InterModel Vigorish' ('IMV'), a metric for
comparing the predictive accuracy of two models for binary
outcomes. The 'IMV' is derived from the expected value of a
bettor using one model's predicted probabilities against those
of a competing model, and is estimated via k-fold
cross-validation. Methods are provided for generalized linear
models, mixed-effects models ('lme4'), and item response theory
models ('mirt'). See Domingue et al. (2025)
