Generalized r squared

WebApproach 1. Because is a variance matrix, we know it is square, symmetric, and positive-de nite. This implies that there exists a square root matrix S such that SS = . Now we multiply our model by S 1: S 1Y = S 1X + S 1 This os a linear regression of S 1Y on S 1X, with the same coe cients as our original regression. WebAlthough the generalized R-squared is commonly recommended for the Cox model, its sensitivity to the proportion of censored values is not often mentioned. In fact, the …

Problem with Cox -Snell: An upper bound less than 1. where . p is the overall proportion of events. The maximum upper bound is .75 when p=.5. When p=.9 or .1, the upper bound is only .48. Simple solution: divide Cox -Snell by its upper bound yielding “max-rescaled R -square” ( Nagelkerke). 首都移転 ミャンマー https://bulkfoodinvesting.com
