I have a data set where the %age of bads are quite low.Can any one suggest a way to balance such a data set using SAS so that the logistic regression run gives a better result? Below is a sample. Thanks in advance!!

ID  X1  X2  X3  X4  X5  Target
 1  87  400 2   0   0   0
 2  70  620 1   0   0   0
 3  66  410 3   0   0   0
 4  85  300 1   0   0   0
 5  100 200 4   0   0   0
 6  201 110 1   0   0   0
 7  132 513 3   0   0   0
