Correlation analysis of features that significantly correlate with MACS (p < 0.05). The correlation-based feature selection includes the elimination of features that have a correlation greater than ±0.85. Correlation values range from -1 to 1 as shown in the heatmap color spectrum. The purple color symbolises a negative correlation, the middle shades indicate a low correlation, whereas the orange section indicates a positive correlation. The color intensity shows the correlation strength.
