Bayesian Inference for Finite Mixture Regression Model Based on Non-Iterative Algorithm

نویسندگان

چکیده

Finite mixtures normal regression (FMNR) models are widely used to investigate the relationship between a response variable and set of explanatory variables from several unknown latent homogeneous groups. However, classical EM algorithm Gibbs sampling deal with this model have weak points. In paper, non-iterative for fitting FMNR is proposed Bayesian perspective. The procedure can generate independently identically distributed samples posterior distributions parameters produce more reliable estimations than sampling. Simulation studies conducted illustrate performance supporting results. Finally, real data analyzed show usefulness methodology.

Bayesian Logistic Regression Model Choice via Laplace-Metropolis Algorithm

Following a Bayesian statistical inference paradigm, we provide an alternative methodology for analyzing a multivariate logistic regression. We use a multivariate normal prior in the Bayesian analysis. We present a unique Bayes estimator associated with a prior which is admissible. The Bayes estimators of the coefficients of the model are obtained via MCMC methods. The proposed procedure...

Bayesian inference on a mixture model with spatial dependence

We introduce a new technique to select the number of components of a mixture model with spatial dependence. It consists in an estimation of the Integrated Completed Likelihood based on a Laplace’s approximation and a new technique to deal with the normalizing constant intractability of the hidden Potts model. Our proposal is applied to a real satellite image.

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
