Test Probabilities in Distribution Platform...version 15 change?When testing probability distributions in the distribution platform (to do a one-way chi-square test), you used to be able to enter any number in the hypothesized probability column and JMP would recalculate to adjust the sum to equal one. This was very helpful since if, for example, I had a ratio set of 9:3:3:1, I could enter 9, 3, 3, 1 and JMP would do the correct math. Now, anytime I enter a number that's not between 0 and 1, I get an error message that these entries have to be between 0 and 1 even though it still suggests it can "rescale" the input probabilities. Am I doing something wrong or is this a "feature" and not a "bug"?
Given that I use this to teach my students about chi-square testing, it is really not helpful to tell them that now they have to do the math.

Re: Test Probabilities in Distribution Platform...version 15 change?In the meantime, the students won't really need to do that much math. In your example of 9:3:3:1, the total is 16. So in the text entry box for the probability type "=9/16", "=3/16", "=3/16", and "=1/16" (without the double-quotes). JMP will do the division for you.
