To set linear constraints for a set of componentsmain topic see also
To set linear constraints for a set of components1 In the Create Mixture Design dialog box, click Components.
2 Click Linear Constraints.
3 In the first column of the table, enter a coefficient for one or more of the components and a lower and/or upper value. Use the arrow key to move down the column and enter desired values. The lower and upper values that you enter must be consistent with value of Single total or the first value in Multiple totals.
You must enter at least one coefficient and an upper or lower value. If you do not enter a coefficient for a component, Minitab assumes it to be zero.
4 Repeat step 3 to enter up to ten different linear constraints on the set of components. Click OK.
