Investigating through the forecasting performance of VAR model for Well C, a) normalized original and forecasted test data points along with their relative errors plotted on the same graph, b) normalized original and forecasted data points for the entire data set including both training and testing data along with their relative errors plotted on the same graph. On both plots, the vertical and horizontal axes show the normalized SCT data and time order (in days), respectively. The original and forecasted data points are shown by small blue circles and orange triangles, respectively, while the relative errors are depicted by small gray diamonds.
