与正态分布或t分布相比,计算F分布的临界值较为复杂。 F分布用于检验两个总体的方差是否存在差异(此时,总体服从正态分布),F-ratioteststatistic称为“F比率检验统计量”。 我们需要比较两个样本的方差,建议将较大的方差作为“分子”,较小的方差作为“分母”。这使得F比率始终大于1.00,能够简化假设检验。 假设实验结...
At least for the tests shown in the website, the chi-square tests are generally right tail tests. Thus if the test statistic is greater than the critical value, then you reject the null hypothesis (aka a significant result). Otherwise you should retain the null hypothesis (note we don’t...
test statistic, most notably in the analysis of variance (ANOVA). Returns the F probability distribution. You can use this function to determine whether two data sets have different degrees of diversity. For example, you can examine the test scores of men and women entering high school, and ...
FTEST returns the#DIV/0!error value if: The number of data points inarray1orarray2is less than 2. The variance ofarray1orarray2is 0 (zero). The FTEST value returned by theLINESTfunction differs from the F-test value returned by FTEST. LINEST returns the F-statistic, whereas FTEST ...

F.INV.RT can be used to return critical values from the F distribution. For example, the output of an ANOVA calculation often includes data for the F statistic, F probability, and F critical value at the 0.05 significance level. To return the critical value of F, use the significance leve...
Excel Assembly: Microsoft.Office.Interop.Excel.dll Returns the inverse of the right-tailed F probability distribution. If p = F_DIST_RT(x,...), then F_INV_RT(p,...) = x. C# 複製 public double F_Inv_RT (double Arg1, double Arg2, double Arg3); Parameters Arg1 Double ...

Summary This paper employs first-order asymptotic theory in order to establish the asymptotic distribution of the F-test statistic for fixed effects, under non-normality of the errors, when N →∞ (the number of cross-sections) and T is fixed (the number of time periods). Three theoretical ...
