get_item_difficulty

Calculates the item difficulty for each case / vignette

Easily analyze and visualize the performance of symptom
checkers. This package can be used to gain comprehensive insights into
the performance of single symptom checkers or the performance of
multiple symptom checkers. It can be used to easily compare these
symptom checkers across several metrics to gain an understanding of
their strengths and weaknesses. The metrics are developed in
Kopka et al. (2023) <doi:10.1177/20552076231194929>.
