  method = NULL,
  bins = 5
)

`pfa_object`	An object of class wizirt_pfa (i.e. from irt_person_fit)
`wizirt_fit`	An object of class wizirt_irt (i.e. from fit_wizirt)
`rownames`	A vector of unique IDs to identify the rows (i.i person IDs).
`predictors`	Either a matrix or dataframe with a row per person and a column per predictor.
`method`	Either 'Reise' (the default for Rasch) or 'Conijn' (2PL default)
