Surprisingly, the sum of the total effects of my parameters are greater than 1 sometimes (see picture below).</P> <P>I did not find anything in the documentation for this. Can someone explain, why the sum of the total effects can be greater than 1?</P> <P>&nbsp;</P> <P>&nbsp; &nbsp;&nbsp;<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ih_0-1614695304639.png" style="width: 400px;"><img src="https://community.jmp.com/t5/image/serverpage/image-id/30882i8BFE7B87D98B76A4/image-size/medium?v=v2&amp;px=400" role="button" title="ih_0-1614695304639.png" alt="ih_0-1614695304639.png" /></span></P> <P>Best,</P> <P>Christian</P> <P>&nbsp;</P> Fri, 09 Jun 2023 00:29:45 GMT christianguhr 2023-06-09T00:29:45Z https://community.jmp.com/t5/Discussions/Why-are-total-effects-sometimes-more-than-1-in-variable/m-p/364333#M61397 <P>Hello,</P> <P>I'm analyzing a DoE and had a look on the variable importance graphs.
