gridpoints

A generic method used to return a vector of grid
 points used for searching local maxima of the gradient funcion.

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>.
