Webthe power (= 1- ,) of the test involves as parameters only the k - 1 nq's. It is worth noting at this point that the right side of (5.1) is symmetric in the n's. Hence the power of the test is also symmetric in the ti's. 6. Unbiased nature of the Fmax test. To prove the unbiased nature of the Fmax test we need to use a lemma which is LEMMA 3. Web1. What you have there is a table of critical values. It only gives tail areas up to 10%; you can use properties of the F to find lower tail values, but the biggest one-tailed p-value you can get from that set of tables will be 10%.
