mixDenBi: Compute Bivariate Marginal Density for a Normal Mixture
Description
mixDenBi
computes the implied bivariate marginal density from a mixture of
normals with specified mixture probabilities and component parameters.
Usage
mixDenBi(i, j, xi, xj, pvec, comps)
Arguments
xi
grid of values of first variable
xj
grid of values of second variable
pvec
normal mixture probabilities
comps
list of lists of components
Value
an array (length(xi)=length(xj) x 2) with density value
Warning
This routine is a utility routine that does not check the
input arguments for proper dimensions and type.
Details
length(comps) is the number of mixture components. comps[[j]] is a list of
parameters of the jth component. comps[[j]]$mu is mean vector; comps[[j]]$rooti
is the UL decomp of \(\Sigma^{-1}\).
