PS 599 --- Fall 2004
This is the website for Statistical Methods in Political Research, which is this introductory course in applied statistics for graduate students in the Political Science department of the University of Michigan.
Section webpage TBA.
Readings that are not online are available for
you to copy on the door of CPS 4253 or on CTools .
An example of how a confidence interval is the acceptance region of a set of null hypothesis
tests is shown in this pdf . If you want to play
with this yourself, you can download the Sweave file here .

1979), pp. 460-480.
This is a survey article concerning recent advances in certain
areas of statistical theory, written for a mathematical audience
with no background in statistics. The topics are chosen to
illustrate a special point: how the advent of the high-speed
computer has affected the development of statistical theory. The
topics discussed include nonparametric methods, the jackknife, the
bootstrap, cross-validation, error-rate estimation in discriminant
analysis, robust estimation, the influence function, censored
data, the EM algorithm, and Cox's likelihood function. The
exposition is mainly by example, with only a little offered in the
way of theoretical development.

This is an invited expository article for The American
Statistician. It reviews the nonparametric estimation of
statistical error, mainly the bias and standard error of an
estimator, or the error rate of a prediction rule. The
presentation is written at a relaxed mathematical level, omitting
most proofs, regularity conditions, and technical details.

Isn't Everyone a Bayesian?
B. Efron The American Statistician,
Vol. 40, No. 1. (Feb., 1986), pp. 1-5.
Originally a talk delivered at a conference on Bayesian statistics,
this article attempts to answer the following question: why is most
scientific data analysis carried out in a non-Bayesian framework? The
argument consists mainly of some practical examples of data analysis,
in which the Bayesian approach is difficult but Fisherian/frequentist
solutions are relatively easy. There is a brief discussion of
objectivity in statistical analyses and of the difficulties of
achieving objectivity within a Bayesian framework. The article ends
with a list of practical advantages of Fisherian/frequentist methods,
which so far seem to have outweighed the philosophical superiority of
