It was originated from the logistic regression technique. You can use percentile capping (aka Winsorization) for treating outliers in linear regression. It can also be used in logistic regression. It is not restricted to linear regression.Deepanshu Bhallahttps://www.blogger.com/profile/09802839558125192674noreply@blogger.comtag:blogger.com,1999:blog-7958828565254404797.post-81667086229243990592016-07-10T05:50:58.967-07:002016-07-10T05:50:58.967-07:00WOE is used only in the logistic regression only ?...WOE is used only in the logistic regression only ?

For example, you have a income variable and outlier values are more than 500 million dollars. These values would be grouped to a class of (let's say 250-500 million dollars). Later, instead of using the raw values, we would be using WOE scores of each classes. Hope it helps.
