COMPARE <Sample>,#NORMAL,L displays some basic statistics and performs the following tests for normality: Shapiro-Wilk (for sample sizes N<=50) (Conover p.363) D'Agostino (50<=N<=500) Anderson-Darling From version 3.30 the old D'Agostino test has been replaced by a more powerful D'Agostino-Pearson omnibus test. The results are given in the form D'Agostino-Pearson K^2=##.##### P=#.#### (#.### #.###) where K^2 is the test statistics with an approximate Chi^2 distribution with 2 degrees of freedom and P its p value. The numbers in brackets are normal approximations for tests based for skewness and kurtosis, respectively (K^2 is the sum of their squares), giving more information about kind of departure from normal distribution.
