# Efficient MCMC with Caching

This post is part of a running series on Bayesian MCMC tutorials. For updates, follow @StableMarkets. Metropolis Review Metropolis-Hastings is an MCMC algorithm for drawing samples from a distribution known up to a constant of proportionality, $latex p(\theta | y) \propto p(y|\theta)p(\theta)$. Very briefly, the algorithm works by starting with some initial draw $latex \theta^{(0)}$ then running … Continue reading Efficient MCMC with Caching

# Speeding up Metropolis-Hastings with Rcpp

Previous posts in this series on MCMC samplers for Bayesian inference (in order of publication): Bayesian Simple Linear Regression with Gibbs Sampling in R Blocked Gibbs Sampling in R for Bayesian Multiple Linear Regression Metropolis-in-Gibbs Sampling and Runtime Analysis with Profviz The code for all of these posts can be found in my BayesianTutorials GitHub … Continue reading Speeding up Metropolis-Hastings with Rcpp

The necessary and sufficient condition for convergence is that the slope of the supply curve be greater than the absolute value of the slope of the demand curve. If the slope of the supple curve is less, then price and quantity diverge from equilibrium over time.
