F value missing stata you get lots of hits, but also lots of ideas as to what the problem may be. I have had the same … 2021 · A big F, with a small p-value, means that the null hypothesis is discredited, and we would assert that there is a general relationship between the response and predictors (while a small F, with a big p-value indicates that there is no relationship).
A large F ratio means that the variation among group means is more than you’d expect to see by chance. In general, one can reject the null hypothesis if the computed F value for a test is higher than the F critical value. There are little bars that we can see going all the way up to about 5.001.
