Generalized least squares regression

[fezzer]

Is it possible to fit a GLS regression trendline to a graph as opposed to the ordinary least squares(OLS) method provided as standard? I'm just looking to be able to find the slope of a trendline but the data is autocorrelated so OLS trendlines aren't recommended.
Thanks

there's a VBA coded example of GLS in the below link, applied to weighting different rows of a regression differently (weighted regression).

this is just one use of GLS as posted on this forum, but I don't know just what you're looking for

is this for matlab?do you have any other softwares that can use Generalized least squares regression? ((

Nothing to do with matlab. It's VBA code written specifically for a specific problem on this forum.

GLS regression is a statistical technique. Lots of literature on it around. Check Google etc. There's too much fishing in your question for me to say much more. If you want more then please be specific about just what it is that you want.
