Hi, From the look of the report image captured in your first post, you may have a problem with the distribution of the residuals. The model assumes that residuals should be distributed normally: in your case it looks rather asymmetrical but I cannot be sure without actual testing. To do that, the model output, choose Save Residuals, select this new column in your table and test for normality. From the look of it, you may want to try a modification of your your Total Citations with Log X or Log (X + 1) transformation. Considering that you have a very simple model i.e. 1 Y by 1 X, and that the distribution of Ys may be problematic, you may also look into a nonparametric test (e.g. Wilcoxon) in the Fit Y by X > One Way Analysis platform > Nonparametric These are my humble recommendations and input from more seasoned JMP users may be desirable. Best, TS
If Grant Type 2 can only have values of 0, 1, 2, or 3, I would make it a Nominal variable rather than Continuous. An ANOVA approach would be more appropriate, I think. The analysis options would likely make more sense for you, too.
