i´m a new JMP user and I´m trying to perform different sets of general linear model in order to assess the best predictors of different dependent variables. I have read some publications reporting this kind of analyses and the partial eta squared coefficient is also reported as an index of effect size. If I use the standard least squares model in JMP, I get statistics for each independent factor, but I don't know how to obtain any index of effect size for each predictor. Does anybody know how I can get that information? Any clue would be very appreciated.
It's probably too late for you, but for anyone else seeing this question you can calculate it by hand using the Sums of Squares given to you. Here's a great resource on it! How to Calculate Effect Size Statistics
