Multinomial Processing Tree (MPT) Models
Fitting and testing multinomial processing tree models, a
class of statistical models for categorical data that involve
latent parameters. These parameters are often interpreted as
psychological processing variables (Batchelder & Riefer, 1999;
Erdfelder et al., 2009; Riefer & Batchelder, 1988).

Fitting and testing multinomial processing tree models, a
class of statistical models for categorical data with latent
parameters.  These parameters are the link probabilities of a
tree-like graph and represent the cognitive processing steps
executed to arrive at observable response categories
(Batchelder & Riefer, 1999; Erdfelder et al., 2009; Riefer &
Batchelder, 1988).
