RSCAT is currently designed for dichotomous items based on the three-parameter logistic (3PL) model.

Title: RSDA - R to Symbolic Data Analysis
Description: Symbolic Data Analysis (SDA) was proposed by professor
Edwin DIDAY in 1987, the main purpose of SDA is to substitute
the set of rows (cases) in the data table for a concept (second
order statistical unit). This package implements, to the
symbolic case, certain techniques of automatic classification,
