Fig. 11: Effects of war cost on unity and disunity.
From: Human civilization dynamics: why we have different civilization patterns in history
A shows the unity and disunity in different war costs. The numeric mark 0 represents unity, while the numeric mark 1 is the disunity. The color of the heatmap indicates the proportion of unity in 500 simulations. B refers to the result of the Decision Tree, examining the validity of the classification. Each box shows the predicted classification, the predicted probability of correct classification and misclassification, and the percentage of observations.
