[Gnuplot-info] chi2

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

Hello,

When I fit data with the weighting option (xyerror),
I get 
final sum of squares of residuals : 22.7527
rms of residuals      (FIT_STDFIT) = sqrt(WSSR/ndf)    : 1.12429
variance of residuals (reduced chisquare) = WSSR/ndf   : 1.26404

But I never get the 
unweighted sum of squares of residuals (Chi2)
ie.
\sum (f(x_i)-y_i)^2

How, can I make this calculation which is provided with a non weighting
option?

Thank.
