Fig. 6. Regression tree with total deforestation in 2008 as the dependent variable. Values below the nodes represent the percentages of reduction of error, or how much of the variance of the data the division in question was able to explain. The values of the terminal leaves (1, 2, 3, 4, 5, and 6) represent the average area deforested and the number of sample units, respectively.
