假设检验在经济调查中的应用

The Application of Presupposing Examination to Economic Investigation

统计假设检验是借助样本统计量来检验假设的总体参数是否成立的方法,通常要预先根据某些事实假设总体参数 M 等于某一值,然后从总体中抽取样本计算样本统计量,通过比较样本统计量和假设的总体参数值,确定样本统计量是否有充分的证据支持原假设。

Statistical presupposing examination is a method used to examine if the presupposed overall parame- ter is tenable with the help of sample statistics.Usually we should presuppose that the overall parameter equals one certain value based on some facts,and draw samples to calculate the sample statistics.By comparing the sample statistics with the presupposed value of overall parameter,we can determine if the sample statistics has enough proofs to support the presupposed value.
