Visualizing Class Specific Heterogeneous Tendencies using R

RESUMO

In this paper we introduce the R package mccca, which implements multiple-class cluster correspondence analysis (MCCCA) proposed in this http URL et al., (2022). MCCCA is a statistical method that identifies and visualizes heterogeneous tendencies specific to ``classes'' (e.g., gender and nationality) in a low dimensional space. In MCCCA, two kinds of variables, external and active variables, are distinguished. External variables directly define classes whereas the active variables are used to derive class-specific clusters of observations (individuals). In this paper, we show how to apply MCCCA and how to visualize its results using mccca. We illustrate the procedure for performing MCCCA by applying it to two data sets.
