Description:
Infrastructure for psychometric modeling such as data classes (for
item response data and paired comparisons), basic model fitting functions (for
Bradley-Terry, Rasch, parametric logistic IRT, generalized partial credit,
rating scale, multinomial processing tree models), extractor functions for
different types of parameters (item, person, threshold, discrimination,
guessing, upper asymptotes), unified inference and visualizations, and various
datasets for illustration. Intended as a common lightweight and efficient
toolbox for psychometric modeling and a common building block for fitting
psychometric mixture models in package "psychomix" and trees based on
psychometric models in package "psychotree".
