ARIMA Modelling - Identify Model for a Time Series

The first step is to identify a possible model for a given time series. To do so, we need three things: a time series plot of the data, ACF plot and the ACF plot. Analysis of these three plots can help us fairly identify the suitable model.

Observing the Time Series Plot
