Hello all I am trying to understand how correspondence analysis works and am looking for an easy to follow example using numbers as to how it is calculated. I have the Greenacre book which is very theoretical but want something that has some data and the formulas and goes through one step by step. Can anyone recommend a book, place on the internet or paper I can find this?
