PROJECTS (https://github.com/Yan8866 for more details) Lung Cancer Data Analysis(R): Compared four machine learning models: Logistic Regression, Decision Tree, Pruned Tree and Random Forest and then selected the model with the best interpretability and prediction power- Logistic Regression to identify significant predictors of lung cancer and predicted how likely a person will develop lung cancer with certain features. Volatility Analysis of the Returns of S&P500 (R): Built ARCH (1) and GARCH (1, 1) models to analyze the volatility of the returns of S&P500, and predicted the volatility of returns. Credit Card Fraud Detection (Python): Trained Linear Regression, Decision Tree, Random Forest and Support Vector Machine models with Scikit-Learn package, used the models to predict how likely a transaction is fraud, then compared their prediction error rate. Random Forest has the greatest prediction power.

Insurance Fraud Detection (Python): Used packages pandas, numpy, seaborn, matplotlib, Plotly, missingno, Scikit-Learn and XGBoost to analyze an insurance data set with 1000 entries and 40 variables; trained nine classifiers: SVM, KNN, Decision Tree, Random Forest and so on. Decision Tree has the best prediction accuracy with a test accuracy rate of 0.816 TECHNICAL SKILLS
