Likelihood Methods for Testing Group Problem Solving Models with Censored Data.

Peer reviewed

Regal, Ronald R.; Larntz, Kinley – Psychometrika, 1978

Models relating individual and group problem solving solution times under the condition of limited time (time limit censoring) are presented. Maximum likelihood estimation of parameters and a goodness of fit test are presented. (Author/JKS)

Tatsuoka, Kikumi K.; Tatsuoka, Maurice M. – 1985

The study examines the rule space model, a probabilistic model capable of measuring cognitive skill acquisition and of diagnosing erroneous rules of operation in a procedural domain. The model involves two important components: (1) determination of a set of bug distributions (bug density functions representing clusters around the rules); and (2)…
