Being "far from others" bears no relevance at all to how a fit is supposed to handle data points. It's _only_ about how far they are from the model function, and then only in the z direction. > but since I deal with resonances, I am > interested in the converse: something that weights much more points far from > the average. So supply your own weights, instead of letting gnuplot default to them all being equal. The documentation is clear enough about how to do that, I think. If you think otherwise, tell where you got lost. > Is there a way to change automatically the weight of each point in a way > that fitted surface will be closer to them? Of course not! Doing that automatically would render whatever parameter you might end up extracting completely meaningless. |
