The “p” and “q” represent the autoregressive (AR) and moving average (MA) lags just like with the ARMA models. The “d” order is the integration order. It represents the number of times we need to integrate the time series to ensure stationarity, but more on that in just a bit.

WebARIMA (1,0,0) = first-order autoregressive model: if the series is stationary and autocorrelated, perhaps it can be predicted as a multiple of its own previous value, plus a constant. The forecasting equation in this case is. Ŷt = μ + ϕ1Yt-1. …which is Y regressed on itself lagged by one period. This is an “ARIMA (1,0,0)+constant” model.
