Shrinkage estimators for semiparametric regression model

open access: yes, 2021
Semiparametric regression models are extensions of linear regression models to include a nonparametric function of some explanatory variables. In semiparametric regression model researchers often encounter the problem of multicollinearity. In the context

SEMIPARAMETRIC PENALIZED SPLINE REGRESSION [PDF]

open access: yesBulletin of informatics and cybernetics, 2012
In this paper, we propose a new semiparametric regression estimator by using a hybrid technique of a parametric approach and a nonparametric penalized spline method. The overall shape of the true regression function is captured by the parametric part, while its residual is consistently estimated by the nonparametric part.

bsamGP: An R Package for Bayesian Spectral Analysis Models Using Gaussian Process Priors

open access: yesJournal of Statistical Software, 2019
The Bayesian spectral analysis model (BSAM) is a powerful tool to deal with semiparametric methods in regression and density estimation based on the spectral representation of Gaussian process priors. The bsamGP package for R provides a comprehensive set

Maximum likelihood estimation for semiparametric regression models with multivariate interval-censored data. [PDF]

open access: yesBiometrika, 2017
Summary Interval‐censored multivariate failure time data arise when there are multiple types of failure or there is clustering of study subjects and each failure time is known only to lie in a certain interval. We investigate the effects of possibly time‐

Real-Time Semiparametric Regression [PDF]

open access: yesJournal of Computational and Graphical Statistics, 2014
We develop algorithms for performing semiparametric regression analysis in real time, with data processed as it is collected and made immediately available via modern telecommunications technologies. Our definition of semiparametric regression is quite broad and includes, as special cases, generalized linear mixed models, generalized additive models ...

Bayesian variants of some classical semiparametric regression techniques [PDF]

open access: yes, 2004
This paper develops new Bayesian methods for semiparametric inference in the partial linear Normal regression model: y=zβ+f(x)+var epsilon where f(.) is an unknown function.

Multivariate Bayesian Semiparametric Regression Model for Forecasting and Mapping HIV and TB Risks in West Java, Indonesia

open access: yesMathematics, 2023
Multivariate “Bayesian” regression via a shared component model has gained popularity in recent years, particularly in modeling and mapping the risks associated with multiple diseases.

Endogeneity in Semiparametric Threshold Regression [PDF]

open access: yesSSRN Electronic Journal, 2017
This paper estimates threshold regression models with an endogenous threshold variable using a nonparametric control function approach. Assuming diminishing threshold effects, we derive the consistency and limiting distribution of our proposed estimator constructed from the series approximation method for weakly dependent data.
