• Data Analysis for Beta-Carotene Jan-Mar,2013

– Determined how di erent dose levels a ected the serum beta-carotene levels over time.

– Utilized Longitudinal Data Analysis: EDA, linear mixed regression models.

– Utilized cross-validation technique to assess the performance of the model in prediction.

• Data Analysis for Motor Function Jun-Jul 2013

– Determined if the additional strength training helps to improve motor function and to identify significant predictors of changes in motor function.

– Utilized Generalized Linear Regression: linear models and logistic models, confidence intervals, hypothesis tests, AIC, BIC.

– Utilized Deviance, leverages, residuals and influential observations to assess goodness-of-fit.

• Chemical Analysis of crude oil samples from di erent regions Oct-Dec 2013

– Compared individual chemicals present in the soil samples from each of the zones
