Witryna5 cze 2024 · 1 Apart from looking at the formulas, the words purity and impurity are indicative (so long as they are used carefully). ∑ p i 2 is maximal (purity is highest) when there is just one category present and so the sum is the sum of 1 2 and any number of 0 2 and so just 1. 1 − ∑ p i 2 is minimal in the same case (impurity is lowest). – Nick Cox
