DAIG – Data Analysis with Intersection Graphs
The main objective of this work is
to develop a new, graph-based framework for multivariate categorical data
analysis.
This line of research stems from the
work done by Valter Vairinhos in his PhD Thesis, and has evolved into a new
data analaysis framework with great potential and with supporting software.
This page contains the main references and some supporting software.
