Dear Society members and friends,

It is my pleasure to announce that the winners of the Society for Political
Methodology's 2016 Gosnell Prize are Marc Rotkovic (Princeton) and Dustin
Tingley (Harvard) for their paper, "Sparse Estimation with Uncertainty:
Subgroup Analysis in Large Dimensional Designs."  The Gosnell Prize for
Excellence in Political Methodology is awarded for the best work in
political methodology presented at any political science conference during
the preceding year.  Please join me in congratulating Marc and Dustin.

My thanks to prize committee members Michael Peress (Stoneybrook, chair),
Suzanna Linn (Penn State), and Brandon Stewart (Princeton).  Their citation
for the award follows:

"Ratkovic and Tingley "Sparse Estimation with Uncertainty: Subgroup
Analysis in Large Dimensional Designs" proposes a new method, LASSOPlus,
for uncovering conditional, subgroup effects in experiments with multiple
treatments and pretreatment covariates. LASSOPlus does three important
things: it selects relevant effects through a sparse model, automatically
selects the degree of regularization and, in contrast to many prior
methods, provides uncertainty estimates through a Bayesian posterior. The
paper presents the model, uses simulation evidence to demonstrate its
performance relative to a set of alternative strategies, and applies the
method to prior work by Bechtel and Scheve (2013). The authors also provide
the sparsereg R package. The methodological contribution of the paper
coupled with a strong readily available implementation ensures that this
work will have a big impact on the field."

A formal presentation of the award will be made at the Methodology
Section's business meeting at APSA (September 2nd at noon).

Best,

Jeff Lewis
