Question 3,3

+ We want to fit a sarima model to the seasonaly differenciated series. 
Execute the following code, should it be a difference between the two calls 
to the `auto.arima` function ?

```{r}

model_D1 =auto.arima(deaths , D=1)

deaths.diff = diff(deaths, 12)

model_diff = auto.arima(deaths.diff)

```
