%description
Implements methods for functional data analysis based on the epigraph and
hypograph indices. These methods transform functional datasets, whether in
one or multiple dimensions, into multivariate datasets. The transformation
involves applying the epigraph, hypograph, and their modified versions to
both the original curves and their first and second derivatives. The
calculation of these indices is tailored to the dimensionality of the
functional dataset, with special considerations for dependencies between
dimensions in multidimensional cases. This approach extends traditional
multivariate data analysis techniques to the functional data setting. A
key application of this package is the EHyClus method, which enhances
clustering analysis for functional data across one or multiple dimensions
using the epigraph and hypograph indices.
