In statistics, Gibbs sampling or a Gibbs sampler is a Markov chain Monte Carlo (MCMC) algorithm for obtaining a sequence of observations which are approximated from a specified multivariate probability distribution, when direct sampling is difficult. This sequence can be used to approximate the joint distribution (e.g., to generate a histogram of the distribution); to approximate the marginal distribution of one of the variables, or some subset of the variables (for example, the unknown parameters or latent variables); or to compute an integral (such as the expected value of one of the variables). Typically, some of the variables correspond to observations whose values are known, and hence do not need to be sampled.
Gibbs sampling is commonly used as a means of statistical inference, especially Bayesian inference. It is a randomized algorithm (i.e. an algorithm that makes use of random numbers), and is an alternative to deterministic algorithms for statistical inference such as the expectation-maximization algorithm (EM).
As with other MCMC algorithms, Gibbs sampling generates a Markov chain of samples, each of which is correlated with nearby samples. As a result, care must be taken if independent samples are desired. Generally, samples from the beginning of the chain (the burn-in period) may not accurately represent the desired distribution and are usually discarded.
Sino na nakaranas mablocked sa Sun? Bumabalik po ba? Nka 3Gig po ako ngayung araw using TU50 promo same lng sa smart ung kaso, hindi na bumabalik sa 4g ung signal
Posible kaya mga boss na naka registered na yung device ko sa network thats why po lage na block po ang sim using openline modem device?..hindi pa kasi umaabot ng 1gb na consume ko na data block na! :(
ilang bses ng nawawalan ng 3g signal ung tnt sim ko peo na uunblocked ko parn ganito lng yan i-mesaage nyu ang smart communications s fb page nla, gnito sbihin mu
MESAGE TO SMART:
pde pa gawaan ng technical report ung tnt sim ko kc nwla 3g signal eh knnang 5:15am , alcatel flash 2(cp) ang...
