Integrates the maximum likelihood estimator of multivariate data over an appropriate subspace to
produce axis-aligned marginals for use in plot.LogConcDEAD
.

Given a multivariate log-concave maximum likelihood
estimator in the form of an object of class "LogConcDEAD"
and
a margin marg
, this function will compute the marginal
density estimate \hat{f}_{n, \textrm{\tiny{marg}}}
.
The estimate is evaluated at gridlen
equally spaced points in
the range where the density estimate is nonzero. These points are
given in the vector
xo
.
\hat{f}_{n, \textrm{\tiny{marg}}}
is evaluated by
integrating the log-concave maximum likelihood estimator
\hat{f}_n
over the other components. The marginal
density is zero outside the range of xo
.
For examples, see mlelcd
.
xo |
Vector of values at which the marginal density is estimate is computed. |
marg |
Vector of values of the integrated maximum likelihood
estimator at the locations |
