Important Request

Of course it would be a good thing. A table with the values of R ^ 2 or r and thus to be able to compare the different models.
I did not do the Prime statistics app. But the calculator, as seen in the images I attached above, calculates when the statistics button is given several things, including the value of R ^ 2 and r. These values should work for something, say Tim, so what I'm saying is that the calculator makes a table with those values for the 13 models it has and then the user will know which is the best model for the data plotted.
