Multiple Regression
This page will perform basic multiple regression analysis for the case where there are several independent predictor variables, X1, X2, etc., and one dependent or criterion variable, Y. Although the programming on the page will in principle handle any number of variables, in practice you will probably not be able to work with more than five or six. This is because multiple regression is computationally very intensive, and the JavaScript engines of web browsers were not really designed to do heavy-duty mathematical work. At any rate, please note that computation time increases as a function of the factorial of the number of variables. Thus, an analysis involving five variables will take about five times as long as one with only four variables; with six variables, computation time will be about six times as long as with only five variables.
