Description
Samples the nine Heligman-Pollard parameters from the mvnorm distribution for each run of optimizer step where the likelihood for that run exceeds the maximum likelihood from the prior.
Usage

2
samp.postopt(opt.cov.d, opt.mu.d, d.keep, prior, B = 400, B0 = 8000,
d = 10)
Arguments
opt.cov.d
An array containing a covariance matrix for each run of optimizer where the likelihood for that run exceeds the maximum likelihood from the prior.
opt.mu.d
A matrix containing the results of the optimizer step.
d.keep
Number of runs of optimizer where the likelihood for that run exceeds the maximum likelihood from the prior.
prior
A matrix containing the prior distribution (see HP.priors).
B
Sample size at the importance sampling stage.
B0
Sample size of the prior. This is equal to (theta.dim * 1000).
d
Number of optimizer iterations.
Value
H.k
The prior plus new samples.
H.new
The new samples from the multivariate normal.
B1
The number of new samples - should be equal to B * d.keep.
Note
For use within the function HP.mod.
