[Gnuplot-info] sum of squares of residuals

[Patrick D. <pd...@gm...>]

Hello,

When I do not weight my data, I get the following
final sum of squares of residuals : 1.85937

but, when I weight my data, I get:
final sum of squares of residuals : 54.6063

The big difference between the 2 values of the Chi2 indicates me that the
weighting of the data is not entirely correct.
When the data are weighted, if \Sum w(i) = 1, I must get a 
similar Chi2.
How can I get the "weighted final sum of squares of residuals"?

Thank.
