Viewed 332 times 5 $\begingroup$ It is common to break down the total sum of squares (related to the total variance in $y$) in a regression problem, into components. $$ y_i-\bar{y} = (y_i - \hat{y_i} + \hat{y_i} - \bar{y}) = (y_i - \h...
and the cases without events should have low predicted values. Tjur also showed that hisR2(which he called the coefficient of discrimination) is equal to the arithmetic mean of twoR2formulas based on squared residuals, and equal to the geometric mean of two otherR2’s based on squared ...
