Example Using a Contour Function
The data in Fish Patty.jmp is adapted from Cornell (1990) and comes from an experiment to optimize the
texture of fish patties. The columns Mullet, Sheepshead, and Croaker represent what proportion of the
patty came from those fish types. The column Temperature represents the oven temperature used to bake
the patties. The column Rating is the response and is a measure of texture acceptability, where higher is
better. A response surface model was fit to the data and the prediction formula was stored in the column
Predicted Rating. (For more information, see the section on Mixture Profilers in the Modeling and
Multivariate Methods book.)
