Title fitstat_ers -- computes outfit and infit statistics for the conditional maximum likelihood (cml) Rasch model as outlined by Linacre and Wright (2004). See

Syntax fitstat_ers varlist [if] [in] , [excel(filename) latex(name)]

Description fitstat_ers estimates fit statistics for conditional likelihood models, proceeding as if Rasch model assumptions are met. The current Stata module raschtest calculates 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).

Options excel(filename) and latex(filename) output the infit and outfit statistics to tables in their respective formats. In order to use
