R Question

I have a little stupid question about

`forecast`

`library(forecast)`

fit <- auto.arima(WWWusage)

print(fit)

This produces:

`Series: WWWusage`

ARIMA(1,1,1)

Coefficients:

ar1 ma1

0.6504 0.5256

s.e. 0.0842 0.0896

sigma^2 estimated as 9.995: log likelihood=-254.15

AIC=514.3 AICc=514.55 BIC=522.08

So in this case I can see that the model is

`ARIMA(1,1,1)`
