... The F-distribution and test is important in econometrics for testing if sample or regression variances differ. A common use is to test hypothesis concerning multiple coefficients in a regression (more on this in class). The F-test takes on several forms, but in general, it is a variance divided by a ...

... Now, this formula has 2 problems. We cannot know with which t-curve we are working without knowing the sample size (because df = n – 1) and we do not have a value for s until we have taken a sample. So, to determine n we need to know t* and s, but to know t* and s we need to have a sample. We “fix” ...
