Open AccessTesting covariance structures belonging to a quadratic subspace under a doubly multivariate model
A hypothesis related to the block structure of a covariance matrix under the doubly multivariate normal model is studied. It is assumed that the block structure of the covariance matrix belongs to a quadratic ...

Bayesian Survival Analysis with the Extended Generalized Gamma Model: Application to Demographic and Health Survey Data
We extend the existing family of flexible survival models by assembling models scattered across the literature into a more knit form and under the same umbrella. New special cases are obtained not only by cons...

Open AccessOn properties of Toeplitz-type covariance matrices in models with nested random effects
Models that capture symmetries present in the data have been widely used in different applications, with early examples from psychometric and medical research. The aim of this article is to study a random effe...

On Explicit Estimation of the Growth Curve Model with a Block Circular Covariance Structure
Estimation of mean parameters in the growth curve model, when the covariance matrix has a block circular Toeplitz structure, is considered. The purpose of this article is to find the appropriate design matrice...

On estimation in hierarchical models with block circular covariance structures
Hierarchical linear models with a block circular covariance structure are considered. Sufficient conditions for obtaining explicit and unique estimators for the variance–covariance components are derived. Diff...

Association of p73 G4C14-to-A4T14 polymorphism with lung cancer risk
Conflicting results were implicated in both single case-control studies and meta-analyses of the correlation between p73 G4C14-to-A4T14 polymorphism and lung cancer risk. We designed this study to further assess ...
