mixDenBi {bayesm}  R Documentation 
mixDenBi
computes the implied bivariate marginal density from a mixture of normals with specified mixture probabilities and component parameters.
mixDenBi(i, j, xi, xj, pvec, comps)
i 
index of first variable 
j 
index of second variable 
xi 
grid of values of first variable 
xj 
grid of values of second variable 
pvec 
normal mixture probabilities 
comps 
list of lists of components 
length(comps)  is the number of mixture components 
comps[[j]]  is a list of parameters of the j th component 
comps[[j]]$mu  is mean vector 
comps[[j]]$rooti  is the UL decomp of \Sigma^{1}

An array (length(xi)=length(xj) x 2
) with density value
This routine is a utility routine that does not check the input arguments for proper dimensions and type.
