Functions for hypothesis testing in single and double Wishart
settings, based on Roy's largest root. This test statistic is especially
useful in multivariate analysis. The computations are based on results by
R package that implements Chiani's iterative algorithms for computing the distribution of the largest root in single and double Wishart settings.
mprechas been removed. The type of precision is now controlled by the parameter
type = 'double'gives double precision
type = 'multi'gives multiprecision
typeis unspecified is to decide adaptively based on the input parameters which type of precision to choose.
