[Gnuplot-info] points too far from the average not enough considered in the fit procedure

[parigigi <par...@gm...>]

Hi all,

After a long campaign of measurement I got a set of data which I want to
display in a 3D graph.

My main goal is to fit these data with a surface, in order to extract some
parameters. "fit" tool is working, but I don't know how to control it.

Particularly if each point weights equal, the fitting procedure "ignores" a
lot points far from the others, but since I deal with resonances, I am
interested in the converse: something that weights much more points far from
the average.

Is there a way to change automatically the weight of each point in a way
that fitted surface will be closer to them?


Thanks a lot to everyone
