WebR-squared is a measure of how closely the data in a regression line fit the data in the sample. The closer the r-squared value is to 1, the better the fit. An r-squared value of … WebTherefore, the quadratic model is either as accurate as, or more accurate than, the linear model for the same data. Recall that the stronger the correlation (i.e. the greater the accuracy of the model), the higher the R^2. So the R^2 for the quadratic model is greater than or equal to the R^2 for the linear model.
