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.Capture1.PNG

    Backward Elimination is a big memory and time suck when you have lots of attributes. I would check out the Evolutionary one, it tends to be a bit faster.
