Jul 3, 2014 at 3:49 comment added cwharland The class imbalance is such that you don't really want to predict click vs no click. Since almost no one clicks your best result is to simply predict they don't click. Instead, think about predicting for all the users that click...which ad will they click on. This is a much more useful problem.

Jun 30, 2014 at 17:44 comment added aasthetic That is what I meant by how the model does not look good. I think this is due to the sparsity of instances of clicks happening and random nature of event of clicks happening. So how can I go about sampling the data? Also how should I add weights to the parameters for improving the prediction? Sorry for adding more open-ended questions but encountering issues as they come, I also want to ask how to work with large datasets in R?

Jun 30, 2014 at 17:02 comment added aasthetic Sorry,an eg: On trying logit in R with these values: day-28, hour-11,day of the week-7, state-New Mexico, OS-iOS, OS Version-7.0, browser family-Mobile Safari, browser version-7.0, device manufacturer-apple, IP carrier- Comcast, user age-20, gender-male, click happened-yes, predicted probability from GLM in R-0.000000001. In another instance,day-28, hour-12th, day of the week-7, state-Connecticut, OS-iOS, OS version-7.0, browser-mobile safari, browser version-7.0, device manufacturer-apple, IP carrier-Comcast, user age-22, user gender-female,click happened-no, predicted probability-.046

Jun 30, 2014 at 15:52 comment added Air That is a lot of open ended questions to ask all at once. One of the goals of this site is that questions and their answers should be useful to future visitors. Can you be more specific? What looks bad in your linear model? When you tried the logistic model, how did it come out? Were there specific problems?
