rejectsampling {LearnBayes} | R Documentation |
Implements a rejection sampling algorithm for a probability density using a multivariate t proposal density
rejectsampling(logf,tpar,dmax,n,data)
logf |
function that defines the logarithm of the density of interest |
tpar |
list of parameters of t proposal density including the mean m, scale matrix var, and degrees of freedom df |
dmax |
logarithm of the rejection sampling constant |
n |
number of simulated draws from proposal density |
data |
data and or parameters used in the function logf |
matrix of simulated draws from density of interest
