Some Research Projects

Work carried out in Statistics Research at Bell Labs covers many areas. Some are defined to solve open problems in statistical computing, visualization, and methodology, and some are defined in collaboration with the business units of Lucent Technologies. Some of our current and past research projects are listed on this page. Writeups of older work can also be found in our list of Technical Reports.
