We could have found the p-value using a Z-test instead, in the event that we know the population standard deviation. P-values show up in many places, including, as further examples, in linear regression, where p-values assess the significance of model coefficients, or in ANOVA testing. Ta...

但根据Coefficients估算出的回归方程可能存在较大的误差,在第三张子表中更为重要的一列是P-value列,P-value为回归系数t统计量的P值。由表中P-value的值可以发现,自变量房屋总面积的P值小于显著性水平0.05,因此这个自变量与y相关。浴室面积和卧室面积的P值大于显著性水平0.05,说这两个自变量与y相关性较弱,甚至不...
一元线性回归分析（linearregression）又称直线拟合，是处理两个变量之间关系的最简单模型。设有一组试验数据，试验值为xi，yi（i=1，2，…，n），其中ｘ为自变量，ｙ为应变量，若ｘ，ｙ可拟符合合为线直性线关yˆ方系i程，，或即已ˆ知经验公ˆ式x为i直线形式，都 上式为变量ｘ，ｙ的一元线性回归...
第二, 利用SPSS 给出的结果与Excel 也大同小异。当然,SPSS 可以给出更多的统计量,如DW 值。在表示方法上,SPSS 也有一些不同,例如P Value(P 值)用 Sig.(显著性)表征,因为二者等价。只要能够读懂Excel 的回归摘要,就可以读懂SPSS 回归输出结果的大部分内容。
In the regression output above, we can see that for every one-point change in Visa, there is a corresponding 1.36-point change in the S&P 500. We can also see that the p-value is very small (0.000036), which also corresponds to a very large T-test. This indicates that this finding ...
