The analyst knows that the population where the model will be deployed has 5% events and 95% non-events. The analyst also knows that the company's profit margin for correctly targeted events is nine times higher than the company's loss for incorrectly targeted non-event.
Given the following SAS program：
proc logistic data = LOANS des;
model Purchase = Inc Edu;
score data = LOANS_V out = LOANS_VS priorevent = ([color=#FF4000:3mw95lvz]insert x here[/color:3mw95lvz]);
run;
data LOANS_VS;
set LOANS_VS;
Solicit = P_1 > ([color=#FF0000:3mw95lvz]insert Y here[/color:3mw95lvz]);
run;
What X and Y values should be added to the program to correctly score the data?
A. X=40, Y=10
B. X=.05, Y=10
C. X=.05, Y=.40
D. X=.10.Y=05
