有限混合密度可以用来模拟已知或怀疑包含许多独立亚群的种群数据。最常用的是具有高斯（单变量或多变量）成分的混合密度，但具有其他类型成分的混合物也越来越多地用于建模，例如生存时间。本文给出了一个一般性的介绍，这应该有助于考虑在这个问题上的其他更专业的论文时的主题。
Finite mixture densities can be used to model data from populations known or suspected to contain a number of separate subpopulations. Most commonly used are mixture densities with Gaussian (univariate or multivariate) components, but mixtures with other types of component are also increasingly used to model, for example, survival times. This paper gives a general introduction to the topic which should help when considering the other more specialized papers in this issue.
