initial

A generic method used to return an initialization for
 a nonparametric/semiparametric mixture.

Mainly for maximum likelihood estimation of nonparametric
and semiparametric mixture models, but can also be used
for fitting finite mixtures. The algorithms are
developed in Wang (2007)
<doi:10.1111/j.1467-9868.2007.00583.x> and Wang (2010)
<doi:10.1007/s11222-009-9117-z>.
