"Euler and Analysis Situs"
ABSTRACT: Imagine a computer game that is played
on the surface of a not so large planet that might not
be spherical but possibly donut shaped or figure eight
shaped and so on. Can you figure out its shape? You
cannot lift off the planet. You can only use the minimap
but can travel extensively on it and mark points and so on.
This is the year of Euler's 300th birthday; see http://www.maa.org/euler/

"Shrinkage and Lasso/Lars and Related Estimation
Strategies in Partially Linear Models"
ABSTRACT: In this talk, I consider a partially linear model where
the vector of coefficients in the linear part can be partitioned where
first sub-vector is the coefficient vector for main effects (e.g.
treatment effect, genetic effects) and the other is a vector for
Śnuisanceą effects (e.g., age, lab). In this situation, inference about
may benefit from moving the least squares estimate for the full
model in the direction of the least squares estimate without the
nuisance variables (Steinian shrinkage), or to drop the nuisance
variables if there is evidence that they do not provide useful
information (pre-testing). We investigate the asymptotic properties
of Stein-type and pretest semiparametric estimators under
quadratic loss and show that under general conditions a Stein-type
semiparametric estimator improves on the full model conventional
semiparametric least square estimator. We also consider a LASSO type
estimator for partially linear models and give a Monte Carlo simulation
comparison of theses estimators. The comparison shows that shrinkage
method performs better than LASSO when the number of restriction on
parameter space is large.
