First, partial autocorrelation functions (PACFs) were examined in order to observe the potential order of any existing autoregressive (AR) process.
I assessed each of the original time series for the presence and form of autocorrelation by examining its autocorrelation function (ACF) and partial autocorrelation function (PACF; Chatfield, 1984).
Partial autocorrelation and autocorrelation shows that time series has serial correlation or no autocorrelation in specified sample period.
The differences among the three models are the respective characteristics of the model autocorrelation and partial autocorrelation function.
