RESEARCH INTERESTS

My research focuses on the problem of estimating parameters in multivariate normal models. Specifically, I consider bilinear and trilinear regression models in which random errors are normally distributed. For the bilinear regression models, also known as Growth Curve Models, the problem of estimating parameters when the covariance matrix has a Kronecker product structure and some factor matrices are linearly structured, (e.g., banded, intraclass, Toeplitz, circular Toeplitz, special structure with zeros or some mix), is of interest. The interest of considering various structures for the covariance matrices in different statistical models is partly driven by the idea that altering the covariance structure of a parametric model alters the variances of the models estimated mean parameters. For the trilinear regression models, the focus is on the 2-fold growth curve model, i.e., the tensor normal model with a trilinear structure for the mean. I am also interested in multivariate linear models for repeated measures data with application to Small Area Estimation.
