You should perhaps go with the variable-selection method with the least variable exclusion.

Certainly not Stepwise; maybe 'Forward' or 'Backward', or even 'Remove'

Misbahuddin Rafeeq

Many many thanks Mr. Darsh, Dr Alhaji. Now it is very clear to me. Thanks again Mr Darsh, You explained it very well.

Mamunur Rashid

Hi Dr. Rafeeq!

Suppose that you are doing multiple linear regression here depending on your dependent and independent variables. I would suggest go for standard linear regression since no multicollinearity exists.
