Dear Applied Statistics Community,

This week we present Andrew C. Thomas, G-4 Department of Statistics,  who
will present his work on "Symmetry and Competition in State Legislative
Election Systems".  Andrew has provided the following abstract for his

Drawing of legislative districts has historically been conducted by the
legislators themselves; recently, some states have appointed redistricting
commissions, the members of which cannot run for seats in the legislature
for a period afterwards. I demonstrate that current methods, in particular
the Gelman-King model and the JudgeIt R package, can easily diagnose the
state of an electoral map given previous electoral conditions. In
particular, competition increases in states with commissions, but the impact
on symmetry is as yet unclear. I conclude with a discussion on techniques to
improve the resolution and measurement of electoral symmetry within states.

Please join us this Wednesday at 12noon for the presentation and a light
lunch.  We hold the workshop in Room N-354 of CGIS-Knafel (1737 Cambridge

I hope that you will be able to attend


Justin Grimmer
