零一膨胀二项混合回归模型的改进EM算法
EM Algorithm Amendment of Zero-and-one Inflated Binomial Mixture Regression Model
摘要
Abstract
This paper proposes a zero-and-one inflated regression model with"heterogeneity".Since standard EM algorithm will make the parameter estimates converge to local optimum,this paper introduces the MCEM algorithm to address this shortcoming, then the estimation of parameter is setted up for the zero-and-one inflated binomial mixture regression model.Finally,the corre-sponding simulation is given to illustrate the proposed method.关键词
