I have a data set in that variables are 3 variables are: Score_Rating, No_Of_Customer,No_Of_Customer_Percentage. Now Calculated terms are: Modified_model=slop * Score_Rating + intercept. Calibrated_PD= exp(Modified_model)/(1+Modified_model) PIT=No_Of_Customer_Percentage * Calibrated_PD; Then take the sum of PIT as final PIT Number. Pls refer the below code. data pit; set pit_pd; tot_cust=10491; slope=0.4359; PIT=0.0259; run; proc model data=pit; pit=(cust/tot_cust)*(exp(slope * Pool_ID +intcpt)/(1+exp(slope * Pool_ID + intcpt))); fit pit /outest=test3 ; solve pit /data=pit out=test4; run; In the excel i am fixing the value if PIT and find out the value of intercept.
