Correspondence Analysis

Correspondence analysis plays a role similar to factor analysis or principal component analysis for categorical data expressed as a contingency table (e.g. as described in the chi-square test of independence).

Essentially, correspondence analysis decomposes the chi-square statistic of independence into orthogonal factors. This approach is valid even when the cell sizes in the contingency table are less than 5 (or even zero).

  1. Doctor Zainontz, buenos días, muchas gracias, por tan grande beneficio que nos presta a la comunidad de investigadores, con su página. Implementaría Ud. el Análisis de correspondencia múltiple, en una versión siguiente? y el DOE 3^k?

    Dr. Zainontz, good morning, thank you very much, for the great benefit you give us to the research community, with your page. Would you implement the Multiple Correspondence Analysis in a subsequent version? and the DOE 3 ^ k?

  2. Doc, Thankyou very much

  3. Dr thank you very much. Merry Christmas and Happy New year.
