Graph r squared value
WebQ&A about R 2 What does R 2 quantify • The value R 2 quantifies goodness of fit. It compares the fit of your model to the fit of a horizontal line through the mean of all Y values. • You can think of R 2 as the fraction … Web1 Using a JSL script, I plot several variables V1, V2, V3 (and so on) from two conditions A and B against each other to see how well-correlated they are. For example. V1 of A vs. V1 of B. I then send the graphs to a JMP report so all graphs will appear in just one window. In JMP, I use the "Fit Line" command to generate the R square table.
