Hi,

I am trying to calulate R-Square by using Step Wise regression in the attached DataSet

Till now I have cleaned the data by excluding the outliers and also by removing variables :

Garage yrblt ,1stflsf,totrmsabvgrd & Garagecars as they have very high correlation.

Recalculated the Lot frontage as Updated Lot Frontage as lot frontage had a lot of missing variables.

My problem is the that the R-Square Value in the Step Wise regression, Forward, minimum BIC is 1.

What am i doing wrong??
