38. 从结果可以看到F检验统计量和p-value,F-statistic: 5.091 , p-value: 0.0332; F检验统计量等于MS回归除以MS残差。 既然P值小于显著性水平,我们能够推断回归模型比仅使用截距模型拟合数据效果更好。对我们示例来说,使用预测变量学习时间和预考成绩,比不用两个预测变量、只用截距效果更好。这里就是实现整体显著...

error value. The F-test value that is returned by theLINEST functiondiffers from the F-test value that is returned by the FTEST function. LINEST returns the F statistic, whereas FTEST returns the probability. Example Copy the example data in the following table, and paste it in cell A1 ...
What is the F Test Formula? The f test formula can be used to find the f statistic. The f test formula is given as follows: F statistic for large samples: F =σ21σ22σ12σ22 F statistic for small samples: F =s21s22s12s22 ...

five-point numerical formulatruncation errorThis chapter discusses the basic concepts of F statistic. The F statistic, along with the Z , t , and chi-square ( 蠂 2 ) statistics, constitute the group of what might be thought as the basic or fundamental statistics. That is because they ...
If Deg_freedom2 is < 1 or Deg_freedom2 is ≥ 10^10, F.INV.RT returns the #NUM! error value. 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 cri...
F statistic from an F distribution with (number of groups – 1) as the numerator degrees of freedom and (number of observations – number of groups) as the denominator degrees of freedom. These statistics are summarized in the ANOVA table. Formula Review SSbetween=∑[(sj)2nj]−(∑sj)2...
