This site provides an introduction to principal component analysis, beginning with a glossary of important terms before taking the reader through the process of completing a principal component analysis. One limitation to the site is its reliance on Minitab and SPSS for calculations. Users without access to these programs can reproduce the calculations using other software packages, such as the freeware program R. Prior knowledge of basic statistics is assumed; thus, the site is most appropriate for advanced undergraduates and graduate students.
The website is available here .
