https://community.jmp.com/t5/Discussions/How-to-find-all-combinations-of-a-variable/m-p/640461#M83786 <P>Hi! I need to be able to find combinations of a variable that equals a certain number. For example, I have a list of 5 solvents all with different solubility parameters. I need to be able to identify what combination of solvents would equal a solubility parameter of approximately 10 (Ex. 30% solvent A + 70% solvent B = solubility parameter of 10.05).&nbsp; Any ideas om how to achieve this?</P> Thu, 08 Jun 2023 18:11:34 GMT WeightedElk7793 2023-06-08T18:11:34Z https://community.jmp.com/t5/Discussions/How-to-find-all-combinations-of-a-variable/m-p/640461#M83786 <P>Hi!

You can add the Response Limits column property to this Solubility column. Use a Match Target for this property. Then launch the Graph &gt; Profiler on the formula column to solve for the desired value.</P> Fri, 09 Jun 2023 18:26:50 GMT https://community.jmp.com/t5/Discussions/How-to-find-all-combinations-of-a-variable/m-p/640960#M83817 Mark_Bailey 2023-06-09T18:26:50Z
