Query: A Mixture of Coalesced Generalized Hyperbolic Distributions   A mixture of multiple scaled generalized hyperbolic distributions (MMSGHDs)
is introduced. Then, a coalesced generalized hyperbolic distribution (CGHD) is
developed by joining a generalized hyperbolic distribution with a multiple
scaled generalized hyperbolic distribution. After detailing the development of
the MMSGHDs, which arises via implementation of a multi-dimensional weight
function, the density of the mixture of CGHDs is developed. A parameter
estimation scheme is developed using the ever-expanding class of MM algorithms
and the Bayesian information criterion is used for model selection. The issue
of cluster convexity is examined and a special case of the MMSGHDs is developed
that is guaranteed to have convex clusters. These approaches are illustrated
and compared using simulated and real data. The identifiability of the MMSGHDs
and the mixture of CGHDs is discussed in an appendix.
