topic How to find ETA squared effect size for MANOVA? in Discussions https://community.jmp.com/t5/Discussions/How-to-find-ETA-squared-effect-size-for-MANOVA/m-p/19838#M18083 <HTML><HEAD></HEAD><BODY><P>Hello, </P><P></P><P>Does anyone know how to calculate the eta squared value from a manova analysis in JMP? I know that the E and H matrices tab shows the sum of squares for each parameter, but which values do I use to calculate SStotal and SSeffect? In my model, I have 2 control variables (age and gender) and then a two way factorial. If only one of these variables (in addition to both control variables) is significant, and I have two dependent variables for the Manova, do I add all four SS values in the matrix for that particular independent variable to get the SSeffect? </P><P></P><P>Alternatively, is there a way to get effect sizes automatically generated in JMP with MANOVAs instead of trying to do it by hand?</P><P></P><P>Lastly, I have noticed that I get different p-values and SSs when running manovas in R vs JMP. Does anyone know why this is the case?</P><P></P><P>Any thoughts you have would be greatly appreciated!</P></BODY></HTML> Mon, 08 Aug 2016 14:04:29 GMT nsalmano_stanfo 2016-08-08T14:04:29Z How to find ETA squared effect size for MANOVA? https://community.jmp.com/t5/Discussions/How-to-find-ETA-squared-effect-size-for-MANOVA/m-p/19838#M18083 <HTML><HEAD></HEAD><BODY><P>Hello, </P><P></P><P>Does anyone know how to calculate the eta squared value from a manova analysis in JMP?
