One way to monitor curve shape over time is to use the root integrated function square of the difference from a target curve. To do this now, you have to 1) fit a functional model to the target function 2) save the formula with function summaries 3) copy the formula over to the original table 3) create the differencing formula 4) fit a model to the difference 5) fit a functional model to the difference and 6) save the root integrated function square with the summaries 7) create a control chart of the root integrated function square.
It would save time and effort if FDE would do these steps when a target curve is loaded. The control chart could be included with the function summaries report.
