Title	Multiple-Goal EBLUP under an Area-Level Model for Small Area Estimation
Abstract	The area-level model has played a vital role in both the theoretical development and practical implementation of small area estimation. In this study, we propose a multiple-goal empirical best linear unbiased predictor (EBLUP) under an area-level model that simultaneously: (i) improves the estimation of shrinkage factors, (ii) addresses the issue of over-shrinkage in EBLUP, and (iii) eliminates the need for complex bias correction procedures when constructing strictly positive, second-order unbiased mean squared error (MSE) estimators, whether using Taylor series expansion or a single parametric bootstrap method. The proposed methodology is evaluated through a Monte Carlo simulation study and applied to real data. This is a joint work with Prof. Partha Lahiri of the University of Maryland, College Park.

This seminar series is a valuable opportunity for graduate students to get acquainted with the work of more experienced researchers in various mathematical fields. Undergraduate students are also welcome to join, as the talks are intended for non-experts, too. Regardless of your area of research, you can attend the seminar to expand your knowledge and get in touch with the latest developments in mathematics for industry.
