R/pois_gamma.R
sim_pred_gamma_pois.RdSimulates nrep draws from the posterior predictive distribution
of the beta-binomial model described in hef.
This function is called within hef when the argument
nrep is supplied.
sim_pred_gamma_pois(theta_sim_vals, data, nrep)A numeric matrix with nrow(data) columns.
Each row of theta_sim_vals contains binomial success probabilities
simulated from their posterior distribution.
A 2-column numeric matrix: the numbers of successes in column 1 and the corresponding numbers of trials in column 2.
A numeric scalar. The number of replications of the original
dataset simulated from the posterior predictive distribution.
If nrep is greater than nrow(theta_sim_vals) then
nrep is set equal to nrow(theta_sim_vals).
A numeric matrix with nrep columns. Each column contains
a draw from the posterior predictive distribution of the number of
successes.
