My name is Jerzy Wieczorek. I’m a statistician (formerly with the U.S. Census Bureau, now at Carnegie Mellon University) working primarily in small area estimation and Bayesian statistics, and using statistics in humanitarian and volunteer work. I’m also interested in languages and linguistics, education and teaching, cognition, etc.
All opinions expressed on this blog are my own and are not intended to represent those of the U.S. Census Bureau or Carnegie Mellon University.
In addition to this blog, I post on Twitter as @civilstat.
