Yes, something like that is what i mean Tim, I copied your code into the statistical application and it works fine, that's what I mean by doing the HP Prime, that she calculates and chooses the best approach, I think it should not be so difficult if you already did it for a Model as the complete program would be for the 13 models, a little more code, and the calculator would choose the one that has a better fit to the data, it is simply something like that, if the HP 50g exists I do not see why not in the Prime.

Note: I suppose for a lot of points as it does take more processing and amount of memory in the calculator, but the option would be viable for practical life problems for about 20 or 30 points I think the calculator is quite capable and speedy to calculate something so.
