I hope everyone out here is doing well. I am working towards a linear regression model.
I am starting out with 470 variables , most of them are demographics variables by area (zip code). My target variable is website traffic by zip code.
Due to high number of variables and lack of time, I quickly ran stepwise regression, but most of the coefficients were not making sense, which made me believe that the model is mis-specified (one of the short coming of step wise regression).
I am planning to try lasso regression next. If this doesn't work I will have to take a manual approach and cherry pick variables to model, which is time consuming.
Is there anything else I could try. I'll appreciate suggestions. Thank you. I am open to share metadata or sample dataset if interested. Thanks
