posterior_predictive_sample_comparison: Poisson model with gamma prior, compare the two parameters

In nathanxli/BayesPD: Bayesian Problem Driven

Description

Poisson model with gamma prior, compare the two parameters

Usage

posterior_predictive_sample_comparison(sample_size = sample_size,
  gamma_a1 = gamma_a1, gamma_b1 = gamma_b1, gamma_a2 = gamma_a2,
  gamma_b2 = gamma_b2, tildeya_smaller_than_tildeyb = TRUE,
  plot = FALSE)

Arguments

sample_size	How many samples to produce.
gamma_a1	First parameter of theta1.
gamma_b1	Second parameter of theta1.
gamma_a2	First parameter of theta2.
gamma_b2	Second parameter of theta2.
tildeya_smaller_than_tildeyb	How to make the comparison. If FALSE, compute theta1 > theta2.
plot	Whether to plot the figure showing the tendency of probability change.

Value

The probability vector or value

Examples

posterior_predictive_sample_comparison(sample_size = 5000, gamma_a1 = 237, 
gamma_b1 = 20, gamma_a2 = 12*(1:100)+113, gamma_b2 = 13+(1:100), 
tildeya_smaller_than_tildeyb = FALSE, plot = TRUE)
