| Post subject: | Weighted total least squares polynomial fitting |
Hello All, I'm trying to do what I think is a fairly simple problem. I want to do a total least squares fitting of my data f(x) = polynomial of order 3. The y and x data are weighted. I have already used the library to do a linear LS fitting and I understand how to do it with the weighting in the y-dimension. How do I add weighting in the x-dimension? Thanks in advance! |
