How F-static help in finding the importance of the variable?

modeling

#1

I am currently studying about different types of measure which help in selecting the importance of the variable while studying it I find two measure first is R^2 and other is F-static.I am able to understand R^2 but I am not able to understand how F-static affect the selection of the variable.

F-static can also be thought of as a measure of the correlation between genes drawn at different levels of a (hierarchically) subdivided population

@harry- The F-static tells that are there any predictive value in the model in other words is there any variable which helps in predicting the dependent variable.It is very important to measure and we always should check while building our model.

Hope this helps!
