Longitudinal Data Regression Analysis Using Semiparametric Modelling

open access: yesRevstat Statistical Journal
Zhang, Leng and Tang (2015) propose joint parametric modelling of the means, variances, and the correlations by decomposing the correlation matrix via hyperspherical co-ordinates and show that this results unconstrained parameterization, fast ...

Multivariate and semiparametric kernel regression [PDF]

open access: yes, 1997
The paper gives an introduction to theory and application of multivariate and semiparametric kernel smoothing. Multivariate nonparametric density estimation is an often used pilot tool for examining the structure of data. Regression smoothing helps in investigating the association between covariates and responses.

SEMIPARAMETRIC REGRESSION AND GRAPHICAL MODELS

open access: yesAustralian & New Zealand Journal of Statistics, 2009
SummarySemiparametric regression models that use spline basis functions with penalization have graphical model representations. This link is more powerful than previously established mixed model representations of semiparametric regression, as a larger class of models can be accommodated. Complications such as missingness and measurement error are more

Specification and Estimation of Rating Scale Models: With an Application to the Determinants of Life Satisfaction [PDF]

open access: yes
Rating variables indicate the extent to which a quality is present, or absent, in a unit of observation. In this paper, we discuss a class of non-linear regression models for rating dependent variables and their estimation by parametric and ...

An Analysis of Housing Expenditure Using Semiparametric Cross-Section Models [PDF]

open access: yes
In this paper we model expenditure on housing for owners and renters by means of endogenous switching regression models using cross-section data. We explain the share of housing in total expenditure from family characteristics and total expenditure ...

Semiparametric modeling for the cardiometabolic risk index and individual risk factors in the older adult population: A novel proposal.

open access: yesPLoS ONE
The accurate monitoring of metabolic syndrome in older adults is relevant in terms of its early detection, and its management. This study aimed at proposing a novel semiparametric modeling for a cardiometabolic risk index (CMRI) and individual risk ...
