Hello,
I found a little BUG in loess <stats>. It does not receive the iterations
parameter.
It can be debugged in the following way:
THIS IS AN EXCERPT FROM THE CODE:
....
fit <- simpleLoess(y, x, w, span, degree, parametric, drop.square,
normalize, control$statistics, control$surface, control$cell,
iterations, control$trace.hat)
Replace argument iterations with control$iterations.
I found also remarkable differences when comparing loess with PROC LOESS
(in SAS) using the same parameters and variables. It really confuses me.
Where can I report this?
Best regards,
Felix Lamp
