Empirical Bayes Estimator for Poisson-Gamma Parameters
also, kruschke at indiana has some info on this, both online and youtube. (if homework.) if not, more infor will be helpful. ~n

Dear Sir/Madam,
I apologize for any cross-posting. I got a simple question, which I thought
the R list may help me to find an answer. Suppose we have Y_1, Y_2, ., Y_n ~
Poisson (Lambda_i) and Lambda_i ~Gamma(alpha_i, beta_i). Empirical Bayes
Estimator for hyper-parameters of the gamma distr, i.e. (alpha_t, beta_t)
are needed.
y=c(12,5,17,14)
n=4
What about a Hierarchal B ayes estimators?
Any relevant work and codes in R (or S+) is highly appreciated.
Kind regards,
Ali
