Hi,
i'm sorry if my question is a very simple one, but in my view the technical
report to the Mathematica packages is ambiguous here.
How do i specify the weights for a weighted regression ?
To be more precise:
If fi is a function to describe the variances in terms of their expectations,
must i specify the weights wi as wi = fi or wi= 1/fi ??
Thanks for any feedback,
Udo.
