Hi,
I am building GB in SAS eminer with event rate of 3.7% ,after tunning for many iteration model miscllasification rate remain constant no change in the rate,any options/ method to tune and reduce the rate.

You can try using a smaller value for the Leaf Fraction property to possibly improve your model. And if you have more than 20K observations in your training data, you can also try increasing the Node Sample property.
Thank you Wendy.
Good news: We've extended SAS Hackathon registration until Sept. 12, so you still have time to be part of our biggest event yet – our five-year anniversary!
