The pisaRT package contains a small example data set of the Canadian PISA 2018 assessment. The data set consists of
scored responses, raw response times and log transformed response times on item level of the first booklet in the math
domain (M01). Polytomous items haven been
dichotomized by scoring not fully correct responses as incorrect. One item has been removed due to problematic fit and 500 persons have been
randomly selected for this subsample. The data set is available in the long (pisaL) and in the wide format (pisaW).
Log transformed response times have been added to the data as these are frequently used in psychometric response time models.
The original data can be retrieved as the "Cognitive items total time/visits data file" by OECD (2020) from https://www.oecd.org/pisa/data/2018database/. The data is available under the CC-BY-SA license.
There exists a wide variety of models for response times of cognitive data. However, no example data set is readily
available in R packages. pisaRT provides a small example data set on which exemplary analysis can be run.
