Abu Zar Md Shafiullah

Biography

Shafiullah started his PhD in January 2014 at the University of Auckland under the supervision of Dr. Arden Miller and Professor Chris Triggs. He completed his MS and B.Sc. Honors in Statistics (secured 1st class 1st and 1st class 2nd position respectively) from the University of Dhaka, Bangladesh. Shafiullah’s MS thesis “Median-Product Correlation and Regression Estimators: New Robust Estimators for Bivariate Data”, develops a new robust measure of correlation and regression coefficients for bivariate data which contain outliers. It was done under the supervision of Professor Jafar Ahmed Khan of the University of Dhaka. Shafiullah has a number of published articles in the areas of robust statistics, classification, and applications of statistics in business and economics. He is currently interested in the design and analysis of experiments with special focus on analyzing supersaturated and other non-regular factorial designs.

Research | Current

My research involves developing an AIC-type model selection criterion for the analysis of screening experiments. Usually non-regular saturated designs are used in this capacity, since they allow a large number of factors to be investigated using relatively small number of runs. However, the screening designs usually have lack of degrees of freedom and complex aliasing among the effects which complicates the analysis. Moreover, the classical hypothesis tests for the regression coefficients are not possible since the experimental variability cannot be estimated. The proposed APC-criterion analyses the regular and non-regular designs screening experiments while maintaining the strong and weak control of false positive rates at the specified levels. The R-package “APCanalysis” is available in the Comprehensive R Archive Network (CRAN) to apply the criterion for real data applications.
