F-test

The basic steps for running this test are as follows:

1. Formulate the null hypothesis and its alternative. 
2. Choose the lags. These can depend on the amount of data you have. One way to choose lags i and j is to run a model order test. It would be easier to pick up multiple values and run the Granger test to see if the results are the similar for different lag levels.

3. Also identify the f-value. The two equations can be used to find out whether βj = 0 for all lags j.
