Hi, I am new to SAS and would like to use regression to validate the accuracy of the existing probabilty model in EG.
I have data calculated and entered in this way in a data set (there are 90.000+ records):
obs probability actual result
1 0.001 1
2 0.150 0
3 0.950 0
4 0.004 1
5 0.055 0
........
The result is shown by the link to the screen shot. I don't believe I did it right as there are so many error counts. I did not write codes but opened the data set and go under "analyze" and choose "regression" and "linear regression". Can someone show me the proper way to run regression to validate. Thanks!
