Descriptionfitstat_ersestimates fit statistics for conditional likelihood models, proceeding as if Rasch model assumptions are met. The current Stata moduleraschtestcalculates infit and outfit statistics transformed to be normal random variates; this module estimates the un-transformed infit and outfit statistics as outlined by Linacre and Wright (1994).
