Hi!
I am using JMP 16 and trying to use Fit Model -> Custom Estimates and I followed this JMP help page https://www.jmp.com/support/help/en/16.2/#page/jmp/custom-test.shtml#ww1531879
However, I don't understand why one of the comparisons is not shown, the example aims at comparing:
"Suppose that you want to test three contrasts. You want to compare the mean responses for the following:
•treatment A to treatment B
•treatments A and B to the control group
•treatments A and B to the control and placebo groups"
But in the output I only see 3 comparisons, the "Placebo" group is not there. And when I tried to run this or my data set which also includes 4 treatments, it also happens that one of the treatments does not appear in the editable table for the custom test.
Can anyone please help me with this?
Thanks.
The example of three custom tests (contrasts) does not include the Placebo level in any contrast, so there are only three tests and there is no comparison with that level. You have to specify exactly which comparisons you want, including the Placebo level. The level 'Placebo' has not meaning to JMP. It is just a label for a unique factor level. It is not automatically considered in any custom test.
What are the comparisons that you want to make?
