WebhIRT is an R package that implements a class of hierarchical item response theory (IRT) models where both the mean and the variance of the latent “ability parameters” may depend on observed covariates. The current implementation includes both the two-parameter latent trait model for binary data ( hltm () and hltm2 ()) and the graded ...
