Linear weighted regression
 

Hi Jerry,

If I want to do a linear regression with 1/x weighting, how do I calculate the weights for the X data and Y data?

Thanks,

Baylye

Dear Auric,

I am very sorry for your unfriendly answer to Baylye.

Weighted linear regression is still a widely used approach in analytical chemistry and maybe in other fields.

No matter if the post is 13, or 50, or 100 years old!

Baylye's question was very interesting and an answer to it would benefit other interested people.

Best regards,
Gianfranco

****ing Google Groupies. You obviously have no idea what Usenet is or how it
works. In the future, when replying, remove everything you quote after the
"-- ", because that's my signature and has nothing to do with the body of
the post.

I'm not.

He should have started a new thread, and referenced the previous thread.
Bringing an old thread back from the dead -- like you have done -- is not
The Right Thing[tm].

Google Groups is connected to Usenet, which predates GG by a couple DECADES.
The original users eventually came up with rules of etiquette ("netiquette")
that help keep the peace. GG users seem to be deliberately ignorant.
