His 1973 paper introduced a Bayesian framework built on the <Dirichlet process>, a <probability distribution> over probability measures. If the prior parameter measure is $\alpha$, observing $x_1,\ldots,x_n$ changes it to $\alpha+\sum_i\delta_{x_i}$. This conjugate update extends the familiar idea of adding category counts to inference about an entire unknown distribution, providing a foundation for Bayesian <nonparametric statistics>.<A Bayesian Analysis of Some Nonparametric Problems by Thomas S.
