Applications of Item Response Theory in R
By W. Jake Thompson in R workshop psychometrics
February 24, 2020
This workshop provides an overview for applying Item Response Theory (IRT) models in R. This includes estimating IRT models, visualizing the estimated parameters, calculating test-level characteristics, and evaluating model fit. The IRT analyses are primarily conducted using the
mirt package. Along the way, we introduce several
tidyverse functions for transforming and visualizing data.
