Log posterior with Poisson sampling and gamma prior
Computes the logarithm of the posterior density of a Poisson log mean with a gamma prior
logpoissgamma(theta,datapar)
theta |
vector of values of the log mean parameter |
datapar |
list with components data, vector of observations, and par, vector of parameters of the gamma prior |
vector of values of the log posterior for all values in theta
