双峰数据分布的模拟

The Simulation of Two Peak Distribution

双峰数据是我们现实生活中存在的一种数据类型,双峰分布是由两个分布混合而成的.本文先讨论由两个正态分布混合而成的双峰分布.包括双峰数据的预处理,参数的确定,模型的建立及优化,并将这种动态模拟的方法应用于美国黄石公园老忠实泉的喷发时间和等待时间数据的统计分析.

Two peak data is a common data type in our life and bimodal distribution is composed of two distribution.This paper focuses on the bimodal distribution composed of two normal distribution,including data preprocessing,parameter identification,establishment and optimization of model.Finally the method is applied to the dynamic simulation of eruption time and waiting time of old Faithful Geyser in the United States Yellowstone National Park.
