如题,Standard error of mean 与Standard error of the estimate,它们有什么区别?为什么前者是用标准差SD除以【样本数N的算术平方根】,而后者就是SD除以【样本数减去自由度N-k的算术平方根】呢?设有变量A取自样本N,N=900,A的平均数m为45,A的标准差为18,则变量A的估计标准误差为何?它的平均标准误差又为何?

Estimate the standard error of the estimate based on a sampleFigure 1 shows two regression examples. You can see that in Graph A, the points are closer to the line than they are in Graph B. Therefore, the predictions in Graph A are more accurate than in Graph B.Figure...
The standard error of the estimate measures the variability of the: A. predicted y-values around the mean of the observed y-values. B. values of the sample regression coefficient. C. actual dependent variable values about the estimated regression line. 相关知识点: 试题来源: 解析 C 略 反...

The calculation results show that the statistic and monitoring value are fairly identical, multiple correlation coefficients bigger and estimated standard error smaller. 计算结果表明:变形统计值与变形监测值吻合较好,统计复相关系数较大,估计标准误差较小。 更多例句>> 3) estimate of standard error 标准误...
C. actual dependent variable values about the estimated regression line. 正确答案:C 分享到: 答案解析: The standard error of the estimate (SEE) measures the uncertainty in the relationship between the independent and dependent variables and helps gauge the fit of the regression line (the smaller ...
这两个是同一个吗,以后表格出现standard error就默认为SEE吗,不可以认为是自变量的标准误吗 添加评论 0 0 1 个答案 星星_品职助教 · 2021年02月19日 同学你好, 这道题的表格有一部分没显示出来,倒数第二行应该是 Standard error of the estimate,也就是SEE。 到底是系数还是整个方程(estimate)的...
