Mixture Profiler<br />

Remove Contour Grid<br />

removes the contour grid if one is on the plot.<br />

Factor Settings is a submenu of comm<strong>and</strong>s that allows you to save <strong>and</strong> transfer the Mixture Profiler<br />

settings to other parts of JMP. Details on this submenu are found in the discussion of the profiler on<br />

“Factor Settings” on page 565.<br />

Linear Constraints<br />

The Mixture Profiler can incorporate linear constraints into its operations. To do this, a Constraint Table<br />

Script must be part of the data table. See “Linear Constraints” on page 575 for details on creating the Table<br />

Script.<br />

When using constraints, unfeasible regions are shaded in the profiler. Figure 24.32 shows an example of a<br />

mixture profiler with shaded regions due to four constraints. The unshaded portion is the resulting feasible<br />

region. The constraints are below:<br />

• 4*p2+p3≤ 0.8<br />

• p2+1.5*p3≤ 0.4<br />

• p1+2*p2≥ 0.8<br />

• p1+2*p2≤ 0.95<br />

Examples<br />

Single Response<br />

This example, adapted from Cornell (1990), comes from an experiment to optimize the texture of fish<br />

patties. The data is in Fish Patty.jmp. The columns Mullet, Sheepshead <strong>and</strong> Croaker represent what<br />

proportion of the patty came from that fish type. The column Temperature represents the oven temperature<br />

used to bake the patties. The column Rating is the response <strong>and</strong> is a measure of texture acceptability, where
