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 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the...
1. 如果F-statistic的值等于或非常接近1,那么结果是支持零假设的,我们不能拒绝它。 但是我们可以看到,F-statistic比1大很多倍,因此为零假设(所有系数都为零)提供了有力的证据。因此,我们拒绝原假设,并相信至少有一个预测器在预测输出时是有用的。 注意,当预测因子§的数量很大,或者p大于数据样本的数量(n)时,...
