Calculate and monitor integrated difference from target in FDEOne 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.
Statistics and AnalyticsRe: Calculate and monitor integrated difference from target in FDEThis suggestion came out of discussion of data being used for the Regeneron JMP Day. In the pharmaceutical industry, FDA guidelines for Process Validation includes Continuous Process Verification to assure that the process remains in the validated state. In other words, if the process includes curves, you could monitor curves during routine commercial manufacturing and assure there are no shifts or drifts from the curves experienced during validation.
Re: Calculate and monitor integrated difference from target in FDEThis is an important technique for modern semiconductor fabs as well. They monitor tool parameter traces during a processing step and compare them to a reference.
