You can specify the combination of Column B AND Flowrate &gt; 1 as a combination that should be diasllowed.</P> <P>&nbsp;</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Disallowed Combos.png" style="width: 748px;"><img src="https://community.jmp.com/t5/image/serverpage/image-id/32739i7FC0B166F903CC10/image-size/large?v=v2&amp;px=999" role="button" title="Disallowed Combos.png" alt="Disallowed Combos.png" /></span></P> Tue, 11 May 2021 08:56:17 GMT Phil_Kay 2021-05-11T08:56:17Z How to specify a DOE constraint with a categorical and continuous factor? https://community.jmp.com/t5/Discussions/How-to-specify-a-DOE-constraint-with-a-categorical-and/m-p/384054#M63458 <P>In a DOE HPLC optimization study I have a two level categorical factor column (A &amp; B) and a continuous factor flowrate. For column A the flowrate range is 0,5 - 2 ml/min but for flowrate B the range is more narrow i.e. 0,5 - 1 ml/min. How can I make a constraint so that there are no combinations column B with flowrate &gt; 1 ml/min?</P> Thu, 08 Jun 2023 21:04:06 GMT https://community.jmp.com/t5/Discussions/How-to-specify-a-DOE-constraint-with-a-categorical-and/m-p/384054#M63458 frankderuyck 2023-06-08T21:04:06Z Re: How to specify a DOE constraint with a categorical and continuous factor? https://community.jmp.com/t5/Discussions/How-to-specify-a-DOE-constraint-with-a-categorical-and/m-p/384067#M63459 <P>Hi Frank, Disallowed Combinations in Custom Design should enable you to do this.
