Prof. Dr. Samir Khaled Safi is Professor of Statistics at the Islamic University of Gaza, Palestine. He earned his Master and PhD in Statistics from the American University in Washington DC. His research interests are in Time Series Analysis, Mathematical Statistics, Regression Analysis, and Econometrics. He has authored several papers concerning the efficiency of Artificial Neural Networks (ANNs) for forecasting in the presence of autocorrelated disturbances and compare ANNs with the traditional forecasting techniques. He has worked on computer simulations of time series models to determine the efficiency of ANNs in the presence of auto-correlated disturbances, he consider the robustness of various models, including Autoregressive Integrated Moving Average (ARIMA) and Regression models. He published many books, for example, "S-PLUS Programming Language and Applied Statistics", (2009) and "The Efficiency of OLS in the Presence of Auto- correlated Errors", VDM Verlag publisher (2008). In addition, Prof. Safi is the recipient of Departmental Instructorship (2000-2004), Department of Mathematics and Statistics, American University, Washington, DC, USA, Arab Student Aid International scholarship (2001-2004) and Karim Rida Said Foundation scholarship (1997-1998).
