Hi Everyone,
Sorry for the short notice, but the topic of tomorrow's Applied Statistics
Seminar has changed. Instead of "Geoadditive Models", Professor Matthew
Wand will talk on "Respiratory Health and Air Pollution: Additive Mixed
Model Analysis?". The paper can be found on the course webpage.
See you tomorrow!

Hi Everyone!
Sorry for the late notice. Nanny Wermuth of the University of Mainz will
be talking at our applied statistics seminar tomorrow. The topic of her
talk will be:
"On visualization and recursive relations in mathematics and statistics"
Visual impressions can help to remember essential ideas as is recognized
in mathematics with an increasing number of so-called proofs without
words. Recursive relations can help to describe complex structures by
utilisizing previous knowledge and results. For instance, Pascal's
triangle combines both features. It is claimed and explored how building
on both ideas can be fruitfully extended both in mathematics and
statistics.
Copies of related papers can be found on the course webpage.
See you tomorrow!

Hi Everyone,
I hope you all had a good break. This is just a quick reminder that the
Applied Statistics Workshop will be meeting this coming Wednesday January

will be presenting his research.
There are still a number of presentation spaces available for the Spring
Semester so please let me know if you or someone you know might be
interested in presenting.
See you all soon!

Hi Everyone,
In tomorrow's applied statistics seminar, Mitali Das, assistant professor
of economics at Columbia University will present her paper "Estimation of
Models with Endogenous Covariates, without Instrumental Variables".
Although the paper is not being distributed before the seminar you can
find the abstract below.
See you tomorrow!

"Estimation of Models with Endogenous Covariates, without Instrumental
Variables"
Mitali Das
Assistant Professor
Department Economics, Columbia University
ABSTRACT
This paper introduces restrictions from economics into the
estimation of models with endogenous covariates. Under weak conditions
such as Spence-Mirrlees single crossing, it is shows that slope
parameters of standard regressions models, e.g. simple linear, binary
choice, censored and truncated models, are identified. Unlike a very large
literature on estimation of such models, this paper does not depend on
instrumental variables setting them apart from a long line of
methodological and empirical work on structural estimation that began with
Koopmans (1949).
The small sample performance of the estimators is studied in a small scale
simulation study. It is also applied to a returns to education problem. In
this application, it is found that the proposed estimators that use no
instruments yield the same behavioral response as a linear IV estimator in
Card (1995) which uses an instrument known to be ``valid'' in the
empirical literature.

Hi Everyone,
Just in case you haven't noticed, the figures for paper are much easier to
interpret using when viewed in color. Please email me
(shirano(a)fas.harvard.edu) if you would like a color printout of the
figures.
Thanks,
Shigeo
