I have twodimensional data, which I want to fit with a linear regression. I get nice results withoctaveforge/main/optim (http://octave.sf.net) has wpolyfit to do a weighted polynomial fit. It also[p, yf] = polyfit (x, y, 2) And now I need the correlation factor... Is there a nice way to calculate this?It would be also quite good, if anybody knows how to calculate the MSWD (Mean Square Weighted Deviation) for a linear regression?
returns an error estimate for the parameters. Paul Kienzle address@hidden
