A time series given by following
$$X_{t-3} – 2.5X_{t-2} + 2X_{t-1} – 0.5X_{t} = E(t) $$
Can you fit an $\text{ARIMA}(p,d,q)$ model in this ?
I tried bring the $X(t)$ term on the right hand side and dividing the entire equation by its coefficient $0.5$. Don't know what to do next.
$E(t)$ is Random White Noise.
