Efficient semiparametric estimation in generalized partially linear additive models for longitudinal/clustered data

, 2014
We consider efficient estimation of the Euclidean parameters in a generalized partially linear additive models for longitudinal/clustered data when multiple covariates need to be modeled nonparametrically, and propose an estimation procedure based on a ...

The analysis of correlated non-Gaussian outcomes from clusters of size two: non-multilevel-based alternatives? [PDF]

, 2012
In this presentation we discuss the analysis of clustered binary or count data, when the cluster size is two. For Gaussian outcomes, linear mixed models taking into account the correlation within clusters, are frequently used and well understood. Here we

Transfer Learning with General Estimating Equations

We consider statistical inference for parameters defined by general estimating equations under the covariate shift transfer learning. Different from the commonly used density ratio weighting approach, we undertake a set of formulations to make the statistical inference semiparametric efficient with simple inference.

GEE Estimation of a Two-Equation Panel Data Model: An Analysis of Wage Dynamics and the Incidence of Profit-Sharing in West Germany [PDF]

We propose a generalized estimating equations approach to the analysis of the mean and the covariance structure of a bivariate time series process of panel data with mixed continuous and discrete dependent variables.

Does the genotype have a significant effect on the formation of intra-annual density fluctuations? A case study using Larix decidua from Northern Poland.

Frontiers in Plant Science, 2016
Intra-annual density fluctuations (IADFs) can imprint environmental conditions within the growing season and most of the research on IADFs has been focused on their climatic signal.

Criteria to Select a Working Correlation Structure for the Generalized Estimating Equations Method in SAS

, 2014
The generalized estimating equations (GEE) method is popular for analyzing clustered and longitudinal data. It is important to determine a proper working correlation matrix when applying the GEE method since an improper selection sometimes results in ...

Sleeping more than 8 h: a silent factor contributing to decreased muscle mass in Chinese community-dwelling older adults

BMC Public Health
Background Muscle mass loss is an age-related process that can be exacerbated by lifestyle, environmental and other factors, but can be mitigated by good sleep.
