Assessing parameter invariance in item response theorys logistic two item parameter model: A monte carlo investigation
Statistical properties of the ability level estimate (theta) in item response theory (IRT) were investigated through a Monte Carlo investigation, based on data generated with a four cases multifactor design. Dichotomous items and the logistic two-parameter IRT model in a one-dimensional setting have...
