Hi!
I have problems with the function arima(), it takes too much time to run
(15 minuts) it is normal?????
for example I put:
a<-arima(d7,c(0,0,5),seasonal=list(order=c(0,1,2),period=7))
where d7 is a daily time serie with 3600 observations
Are there another function to modelize 2 seasonalities at the same time?
another question :
When I add a matrix to regresion the function arima() shows an error :
Erro en optim(init[mask], armaCSS, method = "BFGS", hessian = FALSE, :
valor no finito provisto por optim
what happen?
how can I do to regres a matrix with artificial variables in the model
sarima?
