Subject:      contrasts in JMP?

I have a course project in which students have to test and explain
the pattern of effects among factors in a 3-way design, with two
quanitative factors.

I show them
how to do this in SAS, using CONTRAST statements, and provide
macros,  %poly for polynomial contrasts, and %inter for polynomial
interactions (lin x lin, lin x quad, quad x lin, etc.)

This year, I've started providing JMPIN for students who cannot get
SAS at home, and want to use JMPIN instead.

They can do most things, but we cannot figure out how they can test
trend or other contrasts in JMP
