Applications of Item Response Theory in R
Example item characteristic curve
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 ( {dplyr}) and visualizing ( {ggplot2}) data.
