Is linear regression the same thing as ordinary least squares in SPSS?

Question

I want to use a linear regression model, but I want to use ordinary least squares, which I think it is a type of linear regression. The software I use is SPSS. It only has linear regression, partial least squares and 2-stages least squares. I have no idea which one is ordinary least squares (OLS).

Answer 1

Yes, although 'linear regression' refers to any approach to model the relationship between one or more variables, OLS is the method used to find the simple linear regression of a set of data.
