package ltm -- version 0.8-0
...ble.
New features include:
* The new functions person.fit() and item.fit() compute p-values for
person- and item-fit statistics for IRT models for dichotomous data.
The `simulate.p.value' argument enables the computation of p-values
based on a Monte Carlo procedure.
* The new function unidimTest() checks the unidimensionality
assumption for dichotomous data IRT models, using a Modified Parallel
Analysis.
* The new function testEquatingData() prepares data-sets for test
equating by common items. In particular, two types of common item
equating are included: alternate form equating (w...
