Random decimals incorporated in mixture screening design
Hi
I wonder why JMP introduces the four highlighted numbers (yellow) in the design (0.025064, 0.024936, 0.025089 and 0.024911)? Why are these four values not 0.025?

Re: Random decimals incorporated in mixture screening design
Hi @Principles77,
Welcome in the Community !
The Custom design platform uses the Coordinate-Exchange Algorithm to create designs based on random points, and then move the coordinates of these random points to improve the design based on defined optimality criterion and converge to a specific design.

The "stange" and very precise values you see are a result of this algorithm computation.
When you make your datatable, you can always change the format of the column and limit the number of decimals (double-click on the factors column, click on Format and set the "Fixed Dec" to the number of decimals you want) :
Hope this response answers your question,
