%description
Distance metrics for mixed-type data consisting of continuous, nominal,
and ordinal variables. This methodology uses additive and product kernels
to calculate similarity functions and metrics, and selects variables
relevant to the underlying distance through bandwidth selection via
maximum similarity cross-validation. These methods can be used in any
distance-based algorithm, such as distance-based clustering. For further
details, we refer the reader to Ghashti and Thompson (2024)
<<doi:10.48550/arXiv.2306.01890>> for dkps() methodology, and Ghashti
(2024) <doi:10.14288/1.0443975> for dkss() methodology.
