WebSep 29, 2024 · Goodness of Fit Example. Goodness of fit is a component of regression analysis, which is a statistical method used in finance and a variety of other fields to make predictions based on observed values. In other words, it is a measure of how correlated a group of actual observations are to a model's predictions. In the following examples, the ...
