Bayesian extensions on Lasso and adaptive Lasso Tobit regressions [PDF]

open access: yesPeriodicals of Engineering and Natural Sciences (PEN), 2020
Since lasso method launched, a lot of applications and extensions were run on it which made it to become deeply widely used in various discipline. In this paper, we proposed the Scale Mixture of Normals mixing with Rayleigh (SMNR) distribution on their ...

Bayesian adaptive lassos with non-convex penalization [PDF]

open access: yes, 2007
The lasso (Tibshirani,1996) has sparked interest in the use of penalization of the log-likelihood for variable selection, as well as shrinkage. Recently, there have been attempts to propose penalty functions which improve upon the Lassos properties ...

BAYESIAN ANALYSIS OF TOBIT QUANTILE REGRESSION WITH ADAPTIVE LASSO PENALTY IN HOUSEHOLD EXPENDITURE FOR CIGARETTE CONSUMPTION [PDF]

open access: yesJurnal Statistika Universitas Muhammadiyah Semarang, 2023
Tobit Quantile Regression with Adaptive Lasso Penalty is a quantile regression model on censored data that adds Lasso's adaptive penalty to its parameter estimation. The estimation of the regression parameters is solved by Bayesian analysis.

Adaptive Shrinkage with a Nonparametric Bayesian Lasso

open access: yesJournal of Computational and Graphical Statistics
Modern approaches to perform Bayesian variable selection rely mostly on the use of shrinkage priors. That said, an ideal shrinkage prior should be adaptive to different signal levels, ensuring that small effects are ruled out, while keeping relatively ...

Bayesian adaptive group lasso with semiparametric hidden Markov models [PDF]

open access: yesStatistics in Medicine, 2018
This paper presents a Bayesian adaptive group least absolute shrinkage and selection operator method to conduct simultaneous model selection and estimation under semiparametric hidden Markov models. We specify the conditional regression model and the transition probability model in the hidden Markov model into additive nonparametric functions of ...
