I am Tingting Zhao, a PhD student in Department of Statistics, UBC. mI am trying to use this blog to introduce both the cutting edge statistical methodology and basic statistical knowledge and illustrate some confusing statistical concepts from a student’s perspective. I hope to bring benefit to people who are new and interested in using statistical tools to analyze practical problems and display the complex data. Moreover, I would also to provide some tips about some fancy graphical display of data using ggplot2 which is a widely used statistical software in the community, the examples I use is based on my research work and usually there is some tricky part about the R code that classcial text book may not cover. Finally, I intend to share my understanding of some specific statistical fields and computational implementation of some popular statistical models that my interest lies in.
