"In statistics, an expectation–maximization (EM) algorithm is an iterative method to find (local) maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between … See more The EM algorithm was explained and given its name in a classic 1977 paper by Arthur Dempster, Nan Laird, and Donald Rubin. They pointed out that the method had been "proposed many times in special circumstances" by … See more Although an EM iteration does increase the observed data (i.e., marginal) likelihood function, no guarantee exists that the sequence converges to a maximum likelihood estimator See more EM is frequently used for parameter estimation of mixed models, notably in quantitative genetics. In psychometrics, EM is an important tool for estimating item parameters and latent abilities of item response theory models. With the ability to … See more The EM algorithm is used to find (local) maximum likelihood parameters of a statistical model in cases where the equations cannot … See more The symbols Given the statistical model which generates a set $${\displaystyle \mathbf {X} }$$ of observed data, a … See more Expectation-Maximization works to improve $${\displaystyle Q({\boldsymbol {\theta }}\mid {\boldsymbol {\theta }}^{(t)})}$$ rather than directly improving $${\displaystyle \log p(\mathbf {X} \mid {\boldsymbol {\theta }})}$$.
