Using "Fit Model" I'm predicting my dependent variable using a dichotomous nominal variable "Type" as well as a variable "Sample," which is a random effect (in JMP language that is; some would prefer to call "Sample" a random variable). This tests whether the two "Types" differ on my DV, again taking into account that "Sample" is a random effect.
Interestingly, the sample means for one "Type" are much more spread out compared with the sample means for the other "Type." I can conduct a significance test on the difference in variances using an F test, if I am willing just to use the sample means. But this isn't quite kosher, because the sample means are estimated with error, and ideally, this should be taken into account. I can't figure out how to do this though. Perhaps "Mixed Models" has this ability. (I do have JMP Pro 16.)
This is probably a bit "in the weeds" for this group, but if anyone has any ideas, I'd be grateful. I attach some data. DV=Paraphilia Vector 1, Type is the predictor of interest, and Sample is the random effect.
