OVERVIEW

I am a statistic lecturer at School of Quantitative Sciences. My interest are in robust statistic, inferential statistic, statistical modeling and nonparametric. My previous works investigate the performance and application of various statistical analysis procedures. I am interested in developing robust statistical tests to cases of univariate analysis as an alternative to the classical parametric and nonparametric procedures for comparing groups. Many of my works involve simulation data, but real data analysis also of interest. I am also interested in other areas i.e. quality control and multivariate analysis.
