Extropy, a complementary dual of entropy, is considered in this paper. A Bayesian approach based on the Dirichlet process is proposed for the estimation of extropy. A goodness of fit test is also developed. Many theoretical properties of the procedure are derived. Several examples are discussed to illustrate the approach.

熵的贝叶斯估计和拟合优度检验

熵是熵的互补对偶，本文考虑。提出了一种基于狄利克雷过程的贝叶斯方法来估计熵。还开发了适合度测试。导出了该过程的许多理论性质。讨论了几个例子来说明该方法。
