Profile Summary

My current interest is data analysis. I have experienced using SAS for experimental design, ANOVA analysis with multiple fixed and random variables, and selected appropriate features for model. I have used SAS for 5 years so far and certified as "Base Programmer for SAS 9" by SAS institute at Dec, 2015. I also experienced using R for time series model selection, validation and prediction. Also, I have experienced using R for principle component analysis and Bayesian analysis. I have used R for over 2 years now. Recently, I experienced using Python for machine learning, including regression, classification and clustering. Statistical skills include: • Probability • Statistical Inference • Experimental Design • Linear Regression • Generalized Linear Regression • Bayesian Analysis • Multivariate Analysis • Time Series Analysis • Machine learning
