How is MCMC used in Bayesian statistical models?
MCMC is frequently used for fitting Bayesian statistical models. There are different variations of MCMC, and I’m going to focus on the Metropolis–Hastings (M–H) algorithm.
How are Markov chain Monte Carlo algorithms used in Bayesian inference?
In this article we introduce the main family of algorithms, known collectively as Markov Chain Monte Carlo (MCMC), that allow us to approximate the posterior distribution as calculated by Bayes’ Theorem. In particular, we consider the Metropolis Algorithm, which is easily stated and relatively straightforward to understand.
How does PyMC3 carry out Bayesian inference in Python?
PyMC3 is a Python library (currently in beta) that carries out “Probabilistic Programming”. That is, we can define a probabilistic model and then carry out Bayesian inference on the model, using various flavours of Markov Chain Monte Carlo. In this sense it is similar to the JAGS and Stan packages.
Which is the best course for Bayesian inference?
The handful of very simple Bayesian models that one learns to analyze by hand in a theory course like STAT 5101–5102 are just about all the Bayesian inference one can do by hand. More are found in Box and Tiao, Bayesian Inference in Statistical Analysis (Addison-Wesley, 1973, now out of print) but not much more.

Can you fit a Bayesian model to Stata?
The Bayesian approach to statistics has become increasingly popular, and you can fit Bayesian models using the bayesmh command in Stata. This blog entry will provide a brief introduction to the concepts and jargon of Bayesian statistics and the bayesmh syntax.
Which is a stopping rule and convergence diagnostic for Bayesian inference?
Flegal, Haran, and Jones (2008) argues for using ESS as a stopping rule and convergence diagnostic for Bayesian inference. The estimation of standard errors for quantiles, as would be used in is more complicated. See the package mcmcse for Monte Carlo standard errors of quantiles (though calculated in a different method than rstan ).
