混合逆高斯数据下联合均值与散度模型的参数估计
Parameters Estimation for Joint Mean and Dispersion Models with Mixture Inverse Gaussian Data
摘要
Abstract
The inverse Gaussian distribution is one of the most important statistical data analysis tools for positive skew data.A generalized linear joint mean and dispersion model based on mixture inverse Gaussian distribution is presented.The maximum likehood extimation of unknown parameters is researched using EM algorithm and Fisher-Scoring method.Simulation and practice show that these models and meth-ods are useful and effective.关键词
