Hello, I've recently started using maple 13. I am working on a project for school where I am attempting to use several independent variables to try to predict a single dependent variable. The nature of the project is that there is currently no known answer, and therefore I have been using regression analysis through maple on each individual independent variable on the dependent variable. I was difficult to find a way to preform a goodness of fit test on the data through maple, but I eventually saw a way on this site to compute the R^2 value.
