rtmpt: An R package for fitting response-time extended multinomial processing tree models
Response-time extended multinomial processing tree models (RT-MPT; Klauer and Kellen, Journal of Mathematical Psychology, 82 , 111–130 2018 ) provide estimates of process-completion times for cognitive processes modeled by means of multinomial processing tree (MPT) models (Batchelder and Riefer, Psy...

Zusammenfassung: | Response-time extended multinomial processing tree models (RT-MPT; Klauer and Kellen,
Journal of Mathematical Psychology, 82
, 111–130
2018
) provide estimates of process-completion times for cognitive processes modeled by means of multinomial processing tree (MPT) models (Batchelder and Riefer,
Psychonomic Bulletin & Review, 6
, 57–86
1999
). We present the
R
package rtmpt with which it is possible to fit RT-MPT models easily. The package is free and open source, it can be used with two established MPT syntaxes, and has a number of useful features, such as suppressing process-completion times for specific process outcomes, holding process probabilities constant, and changing some prior parameters. In the background of the
R
package, an altered version of the original
C++
code is used for the MCMC sampling. We provide a guide to using rtmpt, validate the underlying hierarchical Bayesian algorithm of rtmpt using simulation-based calibration and show that previously reported results can be reproduced using rtmpt. |
