Ugh.  Apologies.  I see that for some reason my last message was
truncated at the beginning.  Here it is again:

Correction:  The statistic I describe would range from -1 to 1, with 1
representing perfect reassignment of risk (new model assigns a higher
predicted probability to all those who have events and a lower
probability to all those who do not), to -1 for perfect
mis-reassignment (the converse).
