Correspondence Analysis and Related Methods
Michael Greenacre

The accent in this course is on learning about tools, mostly for visualizing multivariate data, that can be applied to practical problems.
Correspondence analysis (CA) plays a central role in this area because it applies to count data, the most basic form of statistical measurement. Many other data types (raw categorical data, preferences, ratings, continuous measurements, distances) can be recoded in a form suitable for being visulalized using correspondence analysis, hence CA is a versatile framework for data visualization.
