The R package `VCERGM`

implements varying-coefficient random graph models (VCERGMs) on dynamic networks. Available on GitHub.

The R package `DigiPheno`

preprocesses and visualizes smartphone or wearable device data. It also provides functional data analysis approaches to analyze the data. Available on GitHub.

I have taught **P6110: Statistical Computing with SAS** for over 6 semesters. Topics covered in class include:

- data manipulation
- data summary and visualization
- hypothesis testing
- linear regression models
- generalized linear models
- survival data analysis
- longitudinal data analysis

You can download my lecture note here. Relevant SAS example codes are available upon request.

This pdf contains my presentation materials comparing base plots and ggplot in R.

It is a quick tutorial on how to build your own package in R. I presented this at WCM Biostatistics Computing Club, which I founded and maintain. There are biweekly informal meetings of sharing cool coding skills and introducing new packages in various statistical softwares – check out more resources on its website!
