# dad

The data consist of a set of variables measured on several groups of individuals. To each group is associated an estimated probability density function. The **R** package {dad} provides tools to create or manage such data and functional methods (principal component analysis, multidimensional scaling, cluster analysis, discriminant analysis...) for such probability densities.
