A Letter of Recommendation for Nan Xiao

I hope my letter could boost this guy up like: I'm not sure if I'm a good observer, but time and time again I feel some people are undervalued, or they were not given better opportunities to show their value. Not surprisingly, I know quite a few such people in the Chinese R/stats community, mainly because of the...
