1996 NSF Summer Symposium:
The Bootstrap

Econometrics Laboratory
University of California, Berkeley


[AGENDA] | [ROSTER] | [LOCAL INFORMATION]


The bootstrap is a method for estimating the distribution of an estimator or test statistic by resampling one's data. It is often much more accurate in finite samples than are the approximations of (first-order) asymptotic distribution theory. First-order approximations to the distributions of statistics used in econometrics are often highly inaccurate. As a result, the true levels of tests and the coverage probabilities of confidence intervals can be very different from nominal levels based on first-order approximations. The bootstrap provides a practical method for overcoming these problems in many situations relevant to economic and statistical applications.

The symposium will include background papers on the theory and application of the bootstrap, papers presenting the results of new research, and computer laboratory sessions in which participants implement bootstrap methods using simulated and real data.

The symposium will take place 30 July 1996 through 6 August 1996 at the University of California, Berkeley. It is being organized by Joel Horowitz of the University of Iowa and Daniel McFadden of the University of California, Berkeley, under the sponsorship of the National Science Foundation and the UC Berkeley Econometrics Laboratory.

Questions and comments may be e-mailed to the symposium's coordinator, Ms. Grace Katagiri, at katagiri@econ.berkeley.edu .

Lunch for the Yosemite group
11:15-12:00 n.; 639 Evans Hall

People going quadratic hill climbing in Yosemite National Park should leave their packs in 639 Evans in the morning. Pick up your lunch around 11:30 and get ready to leave in vanpools promptly at noon.

You'll be on your own for dinner at Curry Village when we arrive in the evening. Other meals during the camping trip will be catered by our gourmet chefs, Dan McFadden and Paul Ruud.

Photographs from Yosemite National Park

A full view of El Capitan as you enter Yosemite. This is a side view of El Capitan. Anyway you view it, that is a large chunk of rock. No one in the group felt inspired to climb it.

A view of Yosemite falls (just the upper part) as you enter the park. The linear stepwise group walked a little bit stiffly when they got back, but everyone seemed to enjoy the falls (Claudia and Moshe Buchinsky, Paul Rilstone, Russell Davidson, and Yuichi Kitamura).

A view of Half Dome as you approach Curry Village. Our cabins were just below Half Dome and North Dome. The quadratic hill climb group were exhausted but justifiably proud of having climbed Half Dome in record time (Emmanuel Flachaire, Chien-Hua Wu, Helge Blaker, Chris Stomberg, Dan Newlon, and Phillip Leslia).

The Saturday dinner cooks, led by Dan McFadden. The group includes Sue Horowitz, Sumana Bandyopadhyay, Moshe and Claudia Buchinsky, and Grace Katagiri and Brad Itokazu. Here's Joel Horowitz (with Yuichi Kitamura), who organized this year's symposium, enjoying the dinner after a strenuous 16-mile hike in Tuolumne Meadows. The group included Paul Ruud and Bronwyn Hall, who look as though they don't quite know what to do about dinner.
