Unformatted text preview: positive correlation coefficient. The AR1 Model graph of correlogram gives a sine wave function which indicates an alternating positive and negative signs. The Auto-regressice Model of Order 2 correlogram is also computed to know if the AR2 Model is appropriate. In the graph, the correlation coefficient shows an exponential decay. It satisfies stationarity. The highest positive value of correlation coefficient was given at LAG 1 and LAG 10 gives the smallest correlation coefficient value. As a conclusion, the data revealed in the different models performed in the 30 years data of Tarlac City, the autoregressive of order 1 and autoregressive of the order 2 shows the value of RMSE of 565.1061446 and 8429.241021 respectively. This states that the best model is the auto-regressive of order 2 because it has the smallest value of RMSE....
