WitrynaDefine the impurity of $\mathscr{X}_c = C^{-1}(c)$ to be $\phi(c, E(U\mid C(X) = c))$, where $\phi: \mathscr{C} \times \mathscr{U} \rightarrow \mathscr{R}^1$ is a concave function in its second argument. Define the impurity $\Psi$ of the partition as the average impurity of its members: $\Psi(C) = E\phi(C(X), E(U\mid C(X))$.
