Dear Group,
I have come across with the following error while
running HoltWinters().
optim(c(0.3, 0.1, 0.1), error, method = "L-BFGS-B",
lower = c(0, 0, 0), upper = c(1, 1, 1))
It only happens to multiplicative seasonality but not
additive. I read the program but still couldn't
understand it.
Thanks!
