The null hypothesis for both of these tests is that the explanatory variables in the model are … WebThe W you're manually calculating is a χ 2, not an F. Thus 1-pchisq (W,nrow (R)) would be the appropriate command. In addition, note that W ∼ χ 2 with q degrees of freedom (# of joint hypothesis) and 1 q W ∼ F with ( q, d) degrees of freedom ( d being model degrees of freedom). That's why you noticed your statistic being twice the anova F ...
