hi everyone
I have a multiple regression question please
How do we know if one independent variable is a suppressor in the equation?

thanks very much

look for multicollinearity by....

- checking correlation tables - look for high correlations between the IVs (e.g. r>.7)
- look at your VIF and tolerence stats. From memory I think you should have a VIF close to 1 and definitely not as high as 10, and tolerance shouldn't be below .2

And avoid using stepwise method

hi Sneaks!
thanks very much
I will check the values
