According to JMP help: "<SPAN>In the Fit Least Squares report, the Compare Slopes option appears when there is one nominal term, one continuous term, and their interaction effect for the fixed effects. This option produces a report that enables you to compare the slopes in an analysis of covariance (</SPAN><SPAN class="Search_Result_Highlight">ANCOVA</SPAN><SPAN>) model."&nbsp; but I can't find this option...&nbsp;</SPAN></P> Mon, 18 Aug 2025 17:46:25 GMT https://community.jmp.com/t5/Discussions/How-to-get-the-Compare-Slopes-option-to-appear-in-the-Fit-Least/m-p/895095#M105580 Ted1 2025-08-18T17:46:25Z Re: How to get the Compare Slopes option to appear in the Fit Least Squares report? https://community.jmp.com/t5/Discussions/How-to-get-the-Compare-Slopes-option-to-appear-in-the-Fit-Least/m-p/895121#M105581 <P>Fit Y by X launches the Bivariate Fit platfomr.
