DIfference between weights options in lm GLm and gls.
...different.
> lm1
Call:
lm(formula = y ~ x)
Coefficients:
(Intercept) x
0.1183 7.3075
> lm2
Call:
lm(formula = y ~ x, weights = W)
Coefficients:
(Intercept) x
0.04193 7.30660
> lm3
Call:
lm(formula = ys ~ Xs - 1)
Coefficients:
Xs Xsx
0.04193 7.30660
Here ys= y*sqrt(W), Xs<- sqrt(W)*cbind(1,x)
So we can see weights here for lm means the scale for X and y.
But for glm and gls I try
> glm1
Call: glm(formula = y ~ x)
Coefficients:
(Intercept) x
0.1183 7.3075
