Hi
I am trying to get the tricube weights from the loess outputs as I need to
calculate an error function which requires the weight.
So I have used the following example from the R:
cars.lo <- loess(dist ~ speed, cars, span=0.5, degree=1, family="symmetric")
Then i try to get the weights:
cars.lo$weights
[1] 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1 1 1 1 1
The results are all 1 so i dont think that the tricube weighting are set.
May I know what other parameters do i need to tweak to set the weights to
tricube weights? Thank you.
