摘要
目的 具有多层次结构特征的多分类离散数据不宜用常规方法分析 ,本文探讨了多水平多项式模型原理应用。方法 分别从无序和有序分类两种情形 ,研究多水平多项式模型的构造及估计的实现。结果 实例验证多水平模型能给予准确而详尽的结果。结论 对多层次结构的多分类离散数据应使用多水平多项式模型分析 ,在实际应用时 。
Objective It is not suitable to analyze the multiple categroy responsese with hierarchical structured property using ordinary methods.Multilevel multinomial models were discussed in this paper.Methods Studied the model structure and algorithm implement for the unordered and ordered category responses.Results Example verified that the multilevel model can give the accurate and fine results.Conclusion Multilevel multinomial model should be used for multiple category discrete and hierachical structued data,the selection of the model and estimate method should be noticed in practical applications.
