WebQ&A about R 2 What does R 2 quantify • The value R 2 quantifies goodness of fit. It compares the fit of your model to the fit of a horizontal line through the mean of all Y values. • You can think of R 2 as the fraction of the total variance of Y that is explained by the model (equation). With experimental data (and a sensible model) you will always … WebThe process of fitting the best-fit line is called linear regression. The idea behind finding the best-fit line is based on the assumption that the data are scattered about a straight line. …
