RIrtWrappers.jl

This package wraps some R packages for fitting IRT models. The models are returned as item banks as in FitttedItemBanks.jl. The inputs are response matrices, in the same format as provided by ItemResponseDatasets.jl. In particular a dataframe with questions as columns and respondents as rows, with outcomes integer coded.

For example:

• RIrtWrappers.Mirt
• RIrtWrappers.KernSmoothIRT.fit_ks_dichotomous
• RIrtWrappers.Mirt.fit_2pl
• RIrtWrappers.Mirt.fit_3pl
• RIrtWrappers.Mirt.fit_4pl
• RIrtWrappers.Mirt.fit_gpcm
• RIrtWrappers.Mirt.fit_mirt_2pl
• RIrtWrappers.Mirt.fit_monopoly
• RIrtWrappers.Mirt.fit_spline
