The distribution of model averaging estimators and an impossibility result regarding its estimation [PDF]

open access: yes, 2006
The finite-sample as well as the asymptotic distribution of Leung and Barron's (2006) model averaging estimator are derived in the context of a linear regression model. An impossibility result regarding the estimation of the finite-sample distribution of

On the adaptive elastic-net with a diverging number of parameters [PDF]

open access: yes, 2009
We consider the problem of model selection and estimation in situations where the number of parameters diverges with the sample size. When the dimension is high, an ideal method should have the oracle property [J. Amer. Statist. Assoc.

Sparse Conformal Predictors [PDF]

open access: yes, 2009
Conformal predictors, introduced by Vovk et al. (2005), serve to build prediction intervals by exploiting a notion of conformity of the new data point with previously observed data.

Statistical estimation in the proportional hazards model with risk set sampling [PDF]

open access: yes, 2004
Thomas' partial likelihood estimator of regression parameters is widely used in the analysis of nested case-control data with Cox's model. This paper proposes a new estimator of the regression parameters, which is consistent and asymptotically normal ...

Parameter Estimation of the Partially Linear Quantile Regression Model Under Monotonic Constraints

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
The paper brings forward the partially linear quantile regression model by incorporating monotonic constraints, which are common in real‐world relationships between variables. It introduces two novel parameter estimation methods, that is, the coordinate descent method and the profile likelihood method, which eliminate the extensive tuning and simplify ...

Selection of tuning parameters in bridge regression models via Bayesian information criterion

open access: yes, 2012
We consider the bridge linear regression modeling, which can produce a sparse or non-sparse model. A crucial point in the model building process is the selection of adjusted parameters including a regularization parameter and a tuning parameter in bridge

A matrix approach to compare BLUEs under a linear regression model and its two competing restricted models with applications

open access: yesDemonstratio Mathematica
Suppose that a weakly singular linear regression model M{\mathscr{M}} and its two competing restricted models M1{{\mathscr{M}}}_{1} and M2{{\mathscr{M}}}_{2} are given.
