Hi All,
I came across something interesting, that I wasn't really expecting with JMP Pro. Normally, in several platforms, JMP Pro offers the option to run Simulate or Bootstrap to get better estimates and statistics on metrics of interest. However, this appears to not be available when using a BY variable in a supported Platform.
For example, with the Big Class.jmp file, if you do a bivariate fit of :weight by :height and fit a line to it, you get the option to bootstrap or simulate the fit estimates. However, if you do the same bivariate, but include :sex as a BY variable, this option goes away. Is there a reason for this?
Just curious, as I find it odd that this should limit the ability to use either of those techniques. There is a workaround where you can do the normal bivariate fit and then use a local data filter and and select either F or M from :sex.
The first image shows the first example of the regular bivariate fit. The second, when using a BY variable (and that the simulate and bootstrap options are gone when right clicking a statistic). The third shows the regular bivariate fit with a local data filter and the ability to still perform the simulate or bootstrap.
If anyone knows the answer, I'm curious as to why the option goes away with a BY variable.
Thanks!,
DS
