WebIRT Models 3PL Model The famous 3-parameter-logistic (3PL) model was introduced by Birnbaum [1]. The 3PL model uses three item parameters ( a, b, and c) and one ability parameter ( θ) to describe the interaction between an item and a person. The three item parameters are often referred to as the discrimination, difficulty and pseudo-guessing. WebQ1. The parameter estimation uses all available data with ML assuming MAR. The ability (factor score) estimation uses the subject's non-missing items. Q2. That's difficult to say but you do get a SE for the factor score estimate for the …
