WebThis table contains the Cox & Snell R Square and Nagelkerke R Square values, which are both methods of calculating the explained variation.

Therefore, the explained … WebThe definition of R-squared is fairly straight-forward; it is the percentage of the response variable variation that is explained by a linear model. Or: R-squared = Explained variation / Total variation. R-squared is always between 0 and 100%: 0% indicates that the model explains none of the variability of the response data around its mean.
