abstract: 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) <https://doi.org/10.1007/BF03372160>.
