sampledata

A small toy dataset included in the epmfd package, containing
polytomous item responses from simulated persons.

datasets

Analysis of items and persons in data. To identify and remove person misfit in polytomous
item-response data using either 'mokken' or a graded response model (GRM, via 'mirt').
Provides automatic thresholds, visual diagnostics (2D/3D), and export utilities.
Methods build on Mokken scaling as in Mokken (1971, ISBN:9789027968821) and on the
graded response model of Samejima (1969) <doi:10.1007/BF03372160>.
