问题如下:
After doing the regression analysis, if the p-value for both intercept and slope coefficient are smaller than 0.1, and also the Significance F is smaller than 0.1, which of the following conclusions is most likely correct?
选项:
A.The relationship between independent variable and dependent variable is not significant at 0.1 level.
B.The relationship between independent variable and dependent variable is significant at 0.05 level.
C.The relationship between independent variable and dependent variable is significant at 0.1 level.
解释:
C is correct.
考点: Regression Coefficient: F-test.
解析: 由题干可知P-value和Significance F均小于α(0,1),说明自变量和因变量之间的关系在α =10%时是显著的,选择C选项。
P-value和Significance F都是拿来直接和α比的吗?(无论单尾双尾都是直接和阿尔法比?),就是这里正常可能会考虑双尾的话,α要除以二再来和P-value和Significance F比
