摘要
两点分布是是概率论中比较简单但却非常重要的分布之一,处理得好能使得采用常规方法很难处理甚至不可能解决的问题变得异常简单,通过具体实例介绍了两点分布在计算概率、期望以及寻找无偏估计量中的几种灵活运用.
Bernoulli distribution is widely used in applications of probability and statistics.It is an appropriate probability model for many experiments.In such cases,using Bernoulli distribution in analysis can make the calculation much easier,especially when many or cumbersome computations are needed The examples of Bernoulli distribution’s applications in finding unbiased estimators and calculating probability and expected values are also reported.
