中文摘要: |
本文目的是介绍Wald’s检验与SAS实现。具体内容涉及以下9个方面,即一般Wald’s检验、稳健Wald’s检验、约束Wald’s χ2检验、广义Wald’s检验、广义Wald’s对数线性检验、Wald’s F检验、Wald’s校正F检验、Wald’s对数线性F检验和校正Wald’s对数线性F检验。本文通过两个实例并借助SAS软件,实现前述提及的大多数Wald’s检验。 |
英文摘要: |
The purpose of this article was to introduce the Wald?s test and the SAS implementation. The specific contents involved the following nine aspects, namely the general Wald?s test,the robust Wald?s test,the constrained Wald?s χ2 test,the generalized Wald?s test,the generalized Wald?s log-linear test,the Wald?s F test,the Wald?s adjusted F test,the Wald?s log-linear F test and the adjusted Wald?s log-linear F test. The paper used two examples and the SAS software to achieve most of the Wald?s tests mentioned above. |
