The Effect of Risk Factors on Coronary Heart Disease (meta analysis using SAS)

Established the first multivariate regression model using logistic method

Found the interaction among risk factors using the stepwise selection

Tested confounder and interaction using the Mantel-Haenszel and Breslow-Day methods

Successfully found the heterogeneity among the three independent studies and obtained a synthesized odds ratio using meta analysis

Walmart Sales Forecast

Used R to draw a scatter plot and fit a tentative model

Added some polynomial terms in order to increase R square

Did model diagnostics and boxplot to find outliers

Used box-cox and power transformation to make residual to white noise process

Simplified the model using stepwise regression

MTX Prophylactic Treatment Effect on Time to Acute Graft Versus Host Disease

(survival analysis by using SAS)

Fitted a Cox model to provide an unadjusted estimate of the effect of MTX on time to AGVHD

Examined the effect of MTX on time to AGVHD after adjusting for risk group by encoding

Tested interaction between MTX and risk group using likelihood ratio test

Used forward selection to determine best model to test MTX effect on occurrence of AGVHD

Personal Interests

I am an excellent basketball, soccer, Ping-pong, and badminton player. I also like outdoor sports, such like hiking and fishing.
