Virtually every JMP platform allows for the possibility of using a Weighting variable as part of the modeling. However, it would be nice if JMP also provided a capability for creating the weight variables themselves. In survey data, sample populations may not "look" like the target populations. Techniques like Raking (or other similar methods) could be used to create weights to rebalance the sample population to match its intended target population. Both R and Python packages are out there that do this kind of thing. Perhaps one could be converted into an addin or repurposed as an actual JMP platform.
