A “pseudo” R -square. 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).
