%description
Detection of differential item functioning (DIF) among dichotomously
scored items and differential distractor functioning (DDF) among unscored
items with non-linear regression procedures based on generalized logistic
regression models (Hladka & Martinkova, 2020, <doi:10.32614/RJ-2020-014>).
