Non-sampling errors have many different sources, can occur at different stages of the survey and are a result of error contributions of different personnel or agencies Involved in executing the survey. In Interview based surveys,interviewer effectively influences both the response error as well as the response rate. In the present investigation an estimation procedure has been proposed to study the contribution of variance due to response errors as well as non-response errors introduced because of the interviewer. 相似文献

This paper compares analytically the power of the Jayatissa (1977) and Tsurumi (1984) tests for structural change in a heteroskedastic normal linear regression model with two equal-sized independent sub-samples. It is shown that the non-centrality parameter of the Tsurumi test cannot exceed that of the Jayatissa test and some conditions are obtained under which one test dominates the other. 相似文献

基于博弈论的均衡股权结构治理模型研究 总被引:3,自引:3,他引:0
在中国上市公司股权集中度比较高的前提条件下,人们认为国有股"一股独大"的集中股权结构是治理问题存在的根源,建立均衡的股权结构有利于改善公司治理。本文引入多个大股东均衡治理模型,进行完全信息动态博弈的建模和分析,分析的结论是:在目前的公司治理环境、传统文化背景条件下,均衡的股权结构的治理模式未必优于"一股独大"股权结构治理模式。治理结果取决于大股东之间相互博弈过程中的策略选择,而这些股东之间的策略选择与公司治理环境、传统文化、价值观等有关。最后文章在理论分析的基础上给出了一些结论和建议。 相似文献
