Abstract

As a family of statistical models for categorical data, multinomial processingtree (MPT) models have become popular in cognitive psychology over the courseof the past two decades. Classic estimation methods, such as maximumlikelihood estimation (MLE) and model fit test (G2 test), have been applied to MPTmodels widely. Recent development of Bayesian inference suggests a theoreticalalternative for model estimation, though its practical implementation was limiteddue to the difficulties of computation and sampling capacity of the computers. Inthis thesis, I apply Bayesian inference to MPT models, develop the programs thatimplement Bayesian inference for MPT models, and conduct systematiccomparisons between the two approaches in terms of their parameter estimationand model evaluation.
