WebMay 9, 2024 · 1. Compute and plot a local goodness of fit measure. A quick and easy method, that should apply to many such settings, is to examine a local average absolute deviation between the data and their fit. An example appears in the top row of the next figure: the data are on the left and their residuals r i (deviations) are plotted on the right.
