Methodologies for Functional Data Based on the Epigraph and Hypograph Indices.
ehymet
The ehymet (Methodologies for functional data based on the epigraph and hypograph indices) package define the epigraph, the hypograph and their modified versions for functional datasets in one and multiple dimensions. These indices allow to transform a functional dataset into a multivariate one, where usual clustering techniques can be applied. This package implements EHyClus method for clustering functional data in one or multiple dimension.
