Backward elimination problem
Hi, i'am using backward elimination operator for my regression model which contain 80 attributes and 1500 example set. My problem is, after 4 hours of running this model only 10 percent of backward elimination compeleted. i was wondering whether i did somthing wrong with my modeling , or just these process should take this much( approximately 40 hours or more).I used split validation as sub process within linear regression operator.
i just attached a photo of the process.
