Simulation Study for Penalized Bayesian Elastic Net Quantile Regression
نویسندگان
چکیده
Bayesian regression analysis has great importance in recent years, especially the Regularization method, Such as ridge, Lasso, adaptive lasso, elastic net methods, where choosing prior distribution of interested parameter is main idea analysis. By penalizing model, variance estimators are reduced notable and bias getting smaller. The tradeoff between penalized estimator consequently produce more interpretable model with prediction accuracy. In this paper, we proposed new hierarchical for quantile by employing scale mixture normals mixing truncated gamma that stated (Li Lin, 2010) Laplace distribution. Therefore, Gibbs sampling algorithms introduced. A comparison made classical lasso conducting simulations studies. Our comparable gives better results.

Bayesian Quantile Regression with Adaptive Elastic Net Penalty for Longitudinal Data
Longitudinal studies include the important parts of epidemiological surveys, clinical trials and social studies. In longitudinal studies, measurement of the responses is conducted repeatedly through time. Often, the main goal is to characterize the change in responses over time and the factors that influence the change. Recently, to analyze this kind of data, quantile regression has been taken ...

Modern data-rich analyses may call for fitting a large number of nonparametric quantile regressions. For example, growth charts may be constructed for each of a collection of variables, to identify those for which individuals with a disorder tend to fall in the tails of their age-specific distribution; such variables might serve as developmental biomarkers. When such a large set of analyses a...

Quantile regression investigates the conditional quantile functions of a response variables in terms of a set of covariates. Mquantile regression extends this idea by a “quantile-like” generalization of regression based on influence functions. In this work we extend it to nonparametric regression, in the sense that the M-quantile regression functions do not have to be assumed to be linear, but ...
متن کاملBayesian quantile regression
1. Introduction: Recent work by Schennach(2005) has opened the way to a Bayesian treatment of quantile regression. Her method, called Bayesian exponentially tilted empirical likelihood (BETEL), provides a likelihood for data y subject only to a set of m moment conditions of the form Eg(y, θ) = 0 where θ is a k dimensional parameter of interest and k may be smaller, equal to or larger than m. Th...

Tropospheric ozone is one of the six criteria pollutants regulated by the United States Environmental Protection Agency under the Clean Air Act and has been linked with several adverse health effects, including mortality. Due to the strong dependence on weather conditions, ozone may be sensitive to climate change and there is great interest in studying the potential effect of climate change on ...
