{title:Description}

{pstd}
For each variable in {varlist}, {opt sktest} presents a test for
normality based on skewness and another based on kurtosis and then combines
the two tests into an overall test statistic.  {opt sktest} requires a minimum
of 8 observations to make its calculations.

{opt noadjust} suppresses the empirical adjustment made by Royston
to the overall chi-squared and its significance level and presents the
unaltered test as described by D'Agostino, Balanger, and D'Agostino, Jr.
