This post is a continuation of my previous post.
After reading all comments and answer, I think that F-statistics tells us whether explanatory variables in a model is significant or not, as the null hypothesis in F-test is that the variables have no predictive power.
As model 2 has unusually high F-statistics compared to model 1, am I right to say that model 2 is kind of 'weird'?
Also, what does more negative F-statistic imply? Does it have smaller or larger p-value?
