带有约束条件的零一膨胀Poisson回归模型

Zero-and-One-Inflated Poisson Regression Model with Constraints

考虑一类带有一般线性约束条件的零一膨胀Poisson回归模型,给出参数估计的EM(expectation maximization)算法,并利用数值模拟和实际数据分析验证了结果的灵活性和可行性.

We considered a zero-and-one-inflated Poisson(ZOIP)regression model with general linear constraints,and gave an EM(expectation maximization)algorithm to estimate the parameters of the model.The flexibility and feasibility of results are verified by numerical simulation and a real data analysis.
