为啥第29题最后一小问那个求F值分子分母不用除以自由度,而这题需要?
NO.PZ201709270100000201问题如下 1.Consiring Exhibit 1, the F-statistic is closest to: 3.22. 8.06. 30.79. C is correct. The F-statistic isF=RSS/KSSE/[n−(k+1)]=714.169/81583.113/546=89.27122.8995=30.79F=\frac{RSS/K}{SSE/{\lbrack{n-(k+1)}\rbrack}}=\frac{714.169/8}{1583.113/546}=\frac{89.2712}{2.8995}=30.79F=SSE/[n−(k+1)]RSS/K=1583.113/546714.169/8=2.899589.2712=30.79Because F = 30.79 excee the criticF of 1.96, the null hypothesis ththe regression coefficients are all 0 is rejectethe 0.05 significanlevel.为什么分母不是1583.113/549呢

NO.PZ201709270100000201 分子n-k-1为什么等于546,而不是546-8-1
请问这8个K是怎么找到的,我怎么只看见了6个,谢谢!
