FastCUB (version 0.0.2)

fastCUB_package: fastCUB package

Description

The package implements Louis' identity for CUB models for rating data, to retrieve the observed information matrix within the Expectation-Maximization algorithm. On this basis, an acceleration strategy is derived and then a best-subset search through the covariate space for feeling and uncertainty is implemented.
