Han also developed an F-max test based on the square of residuals within treatment,
s2 i = 1 b−1b j=1(yij − ¯ yi· − ¯ y·j + ¯ y··)2. The critical value of Fmax=maxi,k s2 i s2 kcan be expressed as exp ω(α) 2 b−1[1−(t−1)−2]where ω(α)is the 100(1−α)% point of the distribution of the range of a sample of size t from the normal distribution.
