Web5 mag 2016 · @MattCremeens: looking at the documentation for auto_arima in pmdarima, we see a parameter D with the same semantics as the one in R's forecast::auto.arima(). The documentation doesn't say explicitly whether setting D to a value greater than zero forces seasonal differencing, but it seems like the only reasonable interpretation. – WebThe ARIMA (0,1,1) model produces something that's not far off a straight line decrease which seems sensible - the (0,1,1) produces what is essentially a lagged version of the …
