Due to lack in statistics, I could need some help...
-my data set is bivariate with highly correlated errors.
-I need to calculate a weighted linear regression with a standard error on the
slope
-wpolyfit.m takes only dy ...
and my knowlege is too small to use basic statistics.
Is there a possibility to enhance wpolyfit.m or can it be done with gls or ols
?
The reference in literature, I would like to apply is:
York, 1969, Least squares fitting of a straight line with correlated errors,
Earth and Planetary Science Letters 5
alternatively,
Williamson 1968, Least-squares fitting of a straight line, Can. J. Phys. 46
Thanks a lot in advance!
