sample(p_grid, size = n_samples, replace = TRUE, prob = posterior)

# Create a sample space coin <- c("Heads", "Tails") # Simulate 10 coin tosses sample(coin, size = 10, replace = TRUE) # Empirical probability of heads after 1000 tosses set.seed(123) results <- sample(coin, size = 1000, replace = TRUE) mean(results == "Heads") sample(p_grid, size = n_samples, replace = TRUE, prob

Probability is the language of uncertainty. It provides the framework for quantifying the likelihood of events. In mathematical statistics, we often deal with Probability Distributions—mathematical functions that describe the range of possible values and their probabilities.

Unlike frequentist statistics, Bayesian methods incorporate prior knowledge. Packages like rjags and rstan allow users to perform complex Markov Chain Monte Carlo (MCMC) simulations. To run the examples
