Fast Estimation of CUB Models via Louis' Identity

v0.0.4 · Jul 24, 2025 · GPL-2 | GPL-3

Description

For ordinal rating data, consider the accelerated EM algorithm to estimate and test models within the family of CUB models (where CUB stands for Combination of a discrete Uniform and a shifted Binomial distributions). The procedure is built upon Louis' identity for the observed information matrix. Best-subset variable selection is then implemented since it becomes more feasible from the computational point of view.
