Answers are grounded in this paper and cite their sources.

Implication

All models predict SiP-test scores, indicating SIIP and PDL may optimize test settings.

Abstract

All investigated models are useful for predicting SiP-test scores. SIIP and PDL appear suitable for optimising SiP-test settings and estimating critical differences.
