老师好

1. 请问怎么判断这个4.161是否是significant的呢？是查表吗？ 

2. 我查了一个F distribution table k=2, n-k-1=37, critical value=3.25 这个值我查的对不对呢？

3. 考试时没有F distribution table怎么办呢？

4. significance F 是类似于p-value吗？


谢谢

同学你好，

对于题目的这张表而言，就像你说的第四个问题， significance F 是类似于p-value吗？是的，其实这个就是F检验的p值，可以直接跟α进行比较得出结论，所以不会牵扯到查表的问题哈。

而且在二级的case里基本都会给出查表后的数据的，所以也不用担心这个问题。

NO.PZ201709270100000306 问题如下 6. Baseon Exhibit 1, Varn’s best answer to Quinni’s question about the F-statistic is: both inpennt variables are significant the 0.05 level. neither inpennt variable is significant the 0.05 level. least one inpennt variable is significant the 0.05 level. C is correct. Exhibit 1 incates ththe F-statistic of 4.161 is significant the 0.05 level. A significant F-statistic means least one of the inpennt variables is significant. 如题

A significant F-statistic means least one of the inpennt variables is significant. 这里F值显著更准确的应该是all coefficients are joint significant the 0.05 level吗？

F-test的H0是所有b都等于0，现在Pvalue非常小所以证明拒绝原假设，所以说b不等于0，那为什么不选A呢？
