Line in matlab. Definition. R-squared is the proportion of the total sum of squares explained by the model. Rsquared, a property of the fitted model, is a structure with two fields: Ordinary — Ordinary (unadjusted) R-squared. R 2 = S S R S S T = 1 − S S E S S T. Adjusted — R-squared adjusted for the number of coefficients. R a d j 2 = 1 − ( n − 1 n ...
