lrtest.pers

Function to perform a likelihood ratio test for the estimated model 'against' the saturated model for object of class<code>"pers"</code>.

Performs the explicit calculation
-- not estimation! -- of the Rasch item parameters for dichotomous and
polytomous item responses, using a pairwise comparison approach. Person
parameters (WLE) are calculated according to Warm's weighted likelihood
approach.
