Is there any difference in Variable selection for a linear regression vis-a-vis a logistics regression model?

Hm. In my opinion this statement is too general to be true. I recently used Logistic Regression in combination with genetic attribute construction and selection. It indeed improved the results significantly (yes, variables were removed). Despite t…

Profile Information

Short Bio:

Bruce Ratner, Ph.D. is the inventor of the GenIQ Model. The GenIQ Model is a machine learning alternative model to the statistical ordinary least squares and logistic regression models. GenIQ lets the data define the model – automatically data mines for new variables, performs variable selection, and then specifies the model equation – so as to "optimize the decile table," to fill the upper deciles with as much profit/many responses as possible. GenIQ requires no programming (though there is optional control of process), produces models that outdo statistical models, and is for modelers who daringly consider a different model: unsuspected equation, ungainly interpretation, and easy implementation. Put differently, GenIQ seeks to maximize cum lift, a measure of model predictiveness of identifying the upper performing individuals often displayed in a decile table.
