Anderson Darling Test Results. This type of test is useful for testing for normality which is a common assumption used in many statistical tests. This function works for normal exponential logistic or Gumbel Extreme Value Type I distributions.
The simulation results were remarkably consistent with the Anderson-Darling AD test almost always rejecting normality and the Ryan-Joiner RJ test almost always failing to reject normality. 7 It was shown in Anderson and Darling 1954 that 7 can be written as A2 n n 1 n Xn j1 2j1 loguj log 1 unj1 8 where uj F 0 xj and x1 x2 xn is the ordered sample. Minitab does not always display a p-value for the Anderson-Darling test because it does not mathematically exist for certain cases.
