After applying this transformation - all (D-1)-dimensional marginal, univariate distributions are tested using the univariate Anderson-Darling test for normality. - all 0.5 (D-1)(D-2)-dimensional bivariate angle distributions are tested using the Anderson-Darling angle test for normality. - the (D-1)-dimensional radius distribution is tested using the Anderson-Darling radius test for normality. } \value{ \item{res }{ a list including each test result } \item{check }{ information about the rejection of the null hypothesis} \item{alpha}{ the underlying significance level } \item{info}{ further information which is used by the print and summary method. } \item{est}{ \dQuote{standard} for standard estimation and \dQuote{robust} for robust estimation } } \references{ Anderson, T.W. and Darling, D.A.
