beta_sample_comparison: Sampling beta distributions and compare the two variables

In nathanxli/BayesPD: Bayesian Problem Driven

Description

Sampling beta distributions and compare the two variables

Usage

beta_sample_comparison(sample_size, beta_a1, beta_b1, beta_a2, beta_b2,
  theta1_smaller_than_theta2 = TRUE, plot = FALSE)

Arguments

sample_size	How many samples to produce.
beta_a1	First parameter of theta1.
beta_b1	Second parameter of theta1.
beta_a2	First parameter of theta2.
beta_b2	Second parameter of theta2.
theta1_smaller_than_theta2	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. If the variables supplied consists of non-positive numbers, the program will ignore that pair of alpha and beta at the same time.

Examples

beta_sample_comparison(sample_size = 5000, beta_a1 = 58, beta_b1 = 44, 
beta_a2 = 31, beta_b2 = 21)

beta_sample_comparison(sample_size = 6000, beta_a1 = c(58, 58), beta_b1 = c(44, 50), 
beta_a2 = 31, beta_b2 = 21)

beta_sample_comparison(sample_size = 7000, beta_a1 = 58, beta_b1 = 44, 
beta_a2 = c(31, 31), beta_b2 = c(21, 30))

beta_sample_comparison(sample_size = 8000, beta_a1 = 58, beta_b1 = 44, 
beta_a2 = 31, beta_b2 = 21, theta1_smaller_than_theta2 = FALSE)

beta_sample_comparison(sample_size = 8000, beta_a1 = 58, beta_b1 = 44, 
beta_a2 = 31, beta_b2 = 21, theta1_smaller_than_theta2 = FALSE, plot = TRUE)

beta_sample_comparison(sample_size = 9000, beta_a1 = 50:60, beta_b1 = 40:50, 
beta_a2 = 31, beta_b2 = 21, plot = TRUE)

beta_sample_comparison(sample_size = 5000, beta_a1 = 58, beta_b1 = 44, 
beta_a2 = 30:40, beta_b2 = 20:30, plot = TRUE)
