NettetIt is fairly easy to conduct F F -tests in R. We can use the function linearHypothesis () contained in the package car. The output reveals that the F F -statistic for this joint hypothesis test is about 8.01 8.01 and the corresponding p p -value is 0.0004 0.0004. Thus, we can reject the null hypothesis that both coefficients are zero at any ... Nettet17. mar. 2024 · $\begingroup$ @Eco007 ghlt() seems to be focused on multiple-comparison corrections.
