29 jan 2016 we consider sampling methods which follow the so-called markov-chain monte carlo (mcmc) approach.
Markov chain monte carlo (mcmc) algorithms generates a sequence of parameter values whose empirical distribution, approaches the posterior distribution. The generation of the vectors in the chain is done by random numbers (monte carlo) is such way that each new point may only depend on the previous point (markov chain).
Markov chains are simply a set of transitions and their probabilities, assuming no memory of past events. Monte carlo simulations are repeated samplings of random walks over a set of probabilities. You can use both together by using a markov chain to model your probabilities and then a monte carlo simulation to examine the expected outcomes.

Markov chain monte carlo (mcmc) methods for sampling probability density functions (combined with abundant computational resources) have transformed the sciences, especially in performing probabilistic inferences, or fitting models to data. In this primarily pedagogical contribution, we give a brief overview of the most basic mcmc method and some practical advice for the use of mcmc in real.
Markov-chain monte carlo when the posterior has a known distribution, as in analytic approach for binomial data, it can be relatively easy to make predictions, estimate an hdi and create a random sample. Even when this is not the case, we can often use the grid approach to accomplish our objectives.
1 jan 2012 special cases of the model are discussed and a tuned and efficient markov chain monte carlo algorithm is developed to estimate the model.
Markov chain monte carlo is a method to sample from a population with a complicated probability distribution.
It covers everything you need to know before learning about markov chain monte carlo (mcmc). A good introduction to mcmc sampling is the metropolis-hastings algorithm. Before diving in, let’s first define some parameters and functions.

Markov chains: analytic and monte carlo computations introduces the main notions related to markov chains and provides explanations on how to characterize, simulate, and recognize them. Starting with basic notions, this book leads progressively to advanced and recent topics in the field, allowing the reader to master the main aspects of the classical theory.
From the reviews of the second edition: this book is concerned with a probabilistic approach for image analysis, mostly from the bayesian point of view, and the important markov chain monte carlo methods commonly used in this approach. This book will be useful, especially to researchers with a strong background in probability and an interest in image analysis.
Markov chain monte carlo is a method to sample from a population with a complicated probability distribution. Let’s define some terms: sample - a subset of data drawn from a larger population.
Monte carlo simulations are useful for solving problems in which an exact analytic solution is difficult to find or does not exist. A markov chain is a discrete event whose time history (also called a process) has a markov property, which states that future states only depend on the present time.
We describe a markov chain monte carlo analysis of five human y- chromosome microsatellite polymorphisms based on samples from five diverse populations.
We would like to note that coarse-scale models used in the simulations need to be inexpensive but not necessarily very accurate, as our analysis and numerical.
In statistics, markov chain monte carlo (mcmc) methods comprise a class of algorithms for sampling from a probability distribution. By constructing a markov chain that has the desired distribution as its equilibrium distribution, one can obtain a sample of the desired distribution by recording states from the chain.

After some time, the markov chain of accepted draws will converge to the staionary distribution, and we can use those samples as (correlated) draws from the posterior distribution, and find functions of the posterior distribution in the same way as for vanilla monte carlo integration.
Markov chain monte carlo is a method of producing a correlated sample to estimate features of a target distribution through ergodic averages.
Markov chain monte carlo (mcmc) is a sampling method used to estimate expectations with respect to a target distribution.
Markov chain monte carlo (mcmc) is a sampling‐based method for estimating features of probability distributions. Mcmc methods produce a serially correlated, yet representative, sample from the desired distribution. As such it can be difficult to assess when the mcmc method is producing reliable results.
This book teaches modern markov chain monte carlo (mc) simulation techniques step by step. The material should be accessible to advanced undergraduate students and is suitable for a course. It ranges from elementary statistics concepts (the theory behind mc simulations), through conventional.
The markov chain examples of monte carlo runs are well explained. Hopefully, the reader should not have any problem with the concepts. Of course, the actual runs are very compute intensive, but that's why you need a computer.

The name “monte carlo” started as cuteness—gambling was then (around 1950) illegal in most places, and the casino at monte carlo was the most famous in the world—but it soon became a colorless technical term for simulation of random processes. Markov chain monte carlo (mcmc) was invented soon after ordinary monte.

In bayesian analysis we make inferences on unknown quantities of interest ( which could be parameters in a model, missing data, or predictions) by combining.
Markov chain monte carlo (mcmc) simulations allow for parameter estimation such as means, variances, expected values, and exploration of the posterior distribution of bayesian models. To assess the properties of a “posterior”, many representative random values should be sampled from that distribution.

A subclass of mc is mcmc you set up a markov chain whose stationary distribution is the target distribution that you want to sample from. The main thing about many mcmc methods is that due to the fact that you've set up a markov chain, the samples are positively correlated and thereby increases the variance of your integral/expectation estimates.
Although markov chain monte carlo sounds complicated, really it is achieved by this single block of code. Of course, this code is limited in that is only applicable to a very specific situation, namely the task of deriving the posterior given a normal prior and a normal likelihood with known variance.
