Impacts of COVID-19 on a mathematics graduate programme
Published 05/28/2023
International journal of mathematical education in science and technology, 54, 5, 767 - 781
In this study, performance data from students on a mathematics graduate programme from Spring 2019 to Spring 2020 were collected and analysed. The results showed that, if the right course delivery method was implemented, the impact of the coronavirus pandemic (COVID-19) on students' performance could be minimal. Based on the study, some recommendations are made on how to improve students' performances in graduate-level mathematics courses.

Deriving Mixture Distributions Through Moment-Generating Functions
Published 09/2020
Journal of statistical theory and applications, 19, 3, 383 - 390
This article aims to make use of moment-generating functions (mgfs) to derive the density of mixture distributions from hierarchical models. When the mgf of a mixture distribution doesn’t exist, one can extend the approach to characteristic functions to derive the mixture density. This article uses a result given by E.R. Villa, L.A. Escobar, Am. Stat. 60 (2006), 75–80. The present work complements E.R. Villa, L.A. Escobar, Am. Stat. 60 (2006), 75–80 article with many new examples.
