I know a possible work around is to normalize my constraints, but to avoid confusion in reporting the information I would like to have the three components add to 0.883. I have tried to add linear constraints (shown in the attached screen shot) but I get an error. Please advise.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="David_J_0-1616101681146.png" style="width: 400px;"><img src="https://community.jmp.com/t5/image/serverpage/image-id/31361iE6139252803D424C/image-size/medium?v=v2&amp;px=400" role="button" title="David_J_0-1616101681146.png" alt="David_J_0-1616101681146.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="David_J_1-1616101707201.png" style="width: 400px;"><img src="https://community.jmp.com/t5/image/serverpage/image-id/31362i15ABD52762780A1C/image-size/medium?v=v2&amp;px=400" role="button" title="David_J_1-1616101707201.png" alt="David_J_1-1616101707201.png" /></span></P><P>&nbsp;</P><P>&nbsp;</P> Thu, 08 Jun 2023 21:03:17 GMT https://community.jmp.com/t5/Discussions/Making-a-Mixture-Design-that-Does-Not-Sum-to-1-0/m-p/369299#M61905 David_J 2023-06-08T21:03:17Z https://community.jmp.com/t5/Discussions/Making-a-Mixture-Design-that-Does-Not-Sum-to-1-0/m-p/369308#M61906 <P>There is a better way than using constraints.</P> <P>From the red popup triangle by Custom Design choose Advanced Options &gt; Mixture Sum and specify your sum of 0.883.</P> <P>&nbsp;</P> Thu, 18 Mar 2021 21:13:55 GMT https://community.jmp.com/t5/Discussions/Making-a-Mixture-Design-that-Does-Not-Sum-to-1-0/m-p/369308#M61906 Dan_Obermiller 2021-03-18T21:13:55Z https://community.jmp.com/t5/Discussions/Making-a-Mixture-Design-that-Does-Not-Sum-to-1-0/m-p/369634#M61930 <P>Dan, thank you for the insight. I was wondering where that particular function was. This helps me tremendously.&nbsp;</P> Fri, 19 Mar 2021 13:49:52 GMT https://community.jmp.com/t5/Discussions/Making-a-Mixture-Design-that-Does-Not-Sum-to-1-0/m-p/369634#M61930 David_J 2021-03-19T13:49:52Z
