Biography
Gudicha is a prospective Ph.D student at Tilburg University, The Netherlands. His PhD dissertation, supervised under Professor Jeroen K. Vermunt, deals with power and sample size computation methods for both simple mixture models for cross-sectional data and complex mixture models for longitudinal data. The results of this dissertation contribute to the field of mixture modelling in many ways: address factors that affect the power of statistical tests for mixture distributions, but also, considering the case of hypothesis testing for which the asymptotic theory is not warranted, present a method for power/sample size computation. Gudicha got his master in applied statistics from Addis Ababa University and research master in social and Behavioral science from Tilburg University. He has several years of teaching at the University and has also published his research work on high quality journals.
