Hi everyone
I need some help on this topic:
1- simple model one regressor (x)
2- error is heteroskedastic (and residual analysis shows that the error variance increases
with x variable)
3- rerun the analysis dividing both model members by the sqrt(x) - no constant
Eviews runs the white test with a constant
Gretl runs the white test with no constant!
The decision is, of course, different.
Which software is doing it the right way? Eviews, right?
Thanks :)
