r = Pearson correlation coefficient; MAD = mean absolute deviation.
Positive correlation with the advancing CIN grade (r > 0.3) displayed those dwt2 features that evaluate the mean and median of the H-image (dwt2H Mean Value and dwt2H Median Value), and negative correlations displayed those that evaluate the mean and the median of the absolute deviation (dwt2H Mean Absolute Deviation and dwt2H Median Absolute Deviation) (Table 3).
Eight forecasting methods are used and measures of forecasting accuracy, namely, mean absolute deviation (MAD), Mean Absolute Percentage Error (MAPE), and mean square deviation (MSD), are calculated using Minitab 17 package.
The features extracted are Entropy, Energy, Standard Deviation and Mean absolute deviation. The input layer has 4 neurons and output layer has 2 neurons.

The Autoregressive Integrated Moving Average models are used to produce forecasts of long-term total indirect tax and federal revenue collections, which seem to give minimum forecast errors based on a nonparametric Mean Absolute Deviation (MAD) test.
