Hi Helmut!

❝ Hhm, strange. Intercept and slope are not the same as with the other procedures?! Ah, some weighting is used...

You set the weights to 1 with your function call!

❝ If I have time (haha), I will check at R-help about the weighting. If I set all weights=1, I get still different results...

Save your time for nicer things, f.i. NLYW .

Set the call to minimizing the weighted sum of squares in the function to:
fit <- optimize(minfun, c(0.1, 10), x=x, y=y, xv=xstd^2, yv=ystd^2, tol=1.e-8)
and look what happens .

Have a nice weekend.
