Mixture distributions provide a flexible and useful statistical model for many problems arising in scientific research. They are typically used to analyze data that arise from a heterogeneous population or process. When the scientific background is insufficient to determine the appropriate order of a finite mixture model in an application, the number of components or order of the mixture is subject to inference.

混合分布为科学研究中的许多问题提供了一种灵活而有用的统计模型。它们通常用于分析来自异质群体或过程的数据。当科学背景不足以确定有限混合模型在应用中的适当阶数时，可以推断混合物的组分数量或阶数。
