%description
Methods for testing the equality between groups of estimated density
functions. The package implements FDET (Fourier-based Density Equality
Testing) and MDET (Moment-based Density Equality Testing), two new
approaches introduced by the author. Both methods extend an earlier
testing approach by Delicado (2007), "Functional k-sample problem when
data are density functions" <doi:10.1007/s00180-007-0047-y>, which is
referred to as DET (Density Equality Testing) in this package for clarity.
FDET compares groups of densities based on their global shape using
Fourier transforms, while MDET tests for differences in distributional
moments. All methods are described in Anarat, Krutmann and Schwender
(2025), "Testing for Differences in Extrinsic Skin Aging Based on Density
Functions" (Submitted).
