• And now a test of ϕ =1 is a simple t-test of whether the parameter on the “lagged level” of y is equal to zero. This is called a Dickey-Fuller test. Dickey-Fuller Tests • If a constant or trend belong in the equation we must also use D-F test stats that adjust for the impact on the distribution of the test ...

Multiple Hypothesis Testing: The F-test - Matt Blackwell

volving multiple regression coefficients require a different test statistic and a different null distribution. We call the test statistics F 0 and its null distribution the F-distribution, after R.A. Fisher (we call the whole test an F-test, similar to the t-test). Again, there is no reason to be scared of this new test or distribution.
