Multiple robust estimation of marginal structural mean models for unconstrained outcomes
(Wiley Blackwell Publishing, Inc, 2019-03)
We consider estimation, from longitudinal observational data, of the parameters of marginal structural mean models for unconstrained outcomes. Current proposals include inverse probability of treatment weighted and double ...
Exploring the Full-Information Bifactor Model in Vertical ScalingWith Construct Shift
(SAGE, 2012)
To address the lack of attention to construct shift in item response theory (IRT) vertical scaling, a multigroup, bifactor model was proposed to model the common dimension for all grades and the grade-specific dimensions. ...

A time dependent Bayesian nonparametric model for air quality analysis
(Elsevier, 2016)
Air quality monitoring is based on pollutants concentration levels, typically recorded in
metropolitan areas. These exhibit spatial and temporal dependence as well as seasonality
trends, and their analysis demands flexible ...
Performance Evaluation of First-Order Hydraulic Models for COD Removal in Horizontal Subsurface-Flow Constructed Wetlands
(Asce-amer Soc Civil Engineers, 2017-10-01)
The aims of the present study are to verify the performance of four first-order hydraulic models and identify the model that best described the kinetics of the chemical oxygen demand (COD) removal in constructed wetlands. ...

Adaptive LASSO estimation for ARDL models with GARCH innovations
(Taylor & Francis Inc, 2017)
In this paper, we show the validity of the adaptive least absolute shrinkage and selection operator (LASSO) procedure in estimating stationary autoregressive distributed lag(p,q) models with innovations in a broad class ...

Partly linear models on Riemannian manifolds
(Taylor & Francis, 2012-05)
In partly linear models, the dependence of the response y on (xT, t) is modeled through the relationship y = xTβ + g(t) + ε, where ε is independent of (xT, t). We are interested in developing an estimation procedure that ...
