Raymond Carroll and James Hardin will be presenting a one-day short course on Measurement error in nonlinear models. It will follow the second North American Stata Users Group meeting.
The Measurement error in nonlinear models short course is based on the book
Measurement Error in Nonlinear Models|
R. J. Carroll, D. Ruppert and L.A. Stefanski
Chapman and Hall/CRC Press 1995

and is an outgrowth of recent work with StataCorp by the presenters along with Joseph Newton, Henrik Schmiediche, and Tamara Stoner to develop new statistical techniques along with software for estimation in the presence of measurement error.
This course concerns analysis strategies for nonlinear regression problems in which predictors are measured with error. Such problems are commonly known as measurement-error or errors-in-variables modeling, a topic for which there exists a large amount of literature in the case of linear models.
Nonlinear errors-in-variables modeling began in earnest in the early 1980s with the publication of a series of papers on diverse topics: Prentice (1982) on survival analysis; Carroll, Spiegelman, Lan, Bailey and Abbott (1984) and Stefanski and Carroll (1985) on binary regression; Armstrong (1985) on generalized linear models; Amemiya (1985) on instrumental variables; and Stefanski (1985) on estimating equations. In 1987, David Byar and Mitchell Gail organized a workshop on the topic at the National Institutes of Health. In 1989, the results of the workshop were published as a special issue in Statistics in Medicine. Since these early papers, the field has grown dramatically.
The course will cover the following:
In addition to showing how to obtain estimates, methods for obtaining bootstrap, jackknife, and robust ("sandwich") standard errors will be discussed.
A Stata module for estimating these models will be introduced and made available.

Dr. Carroll is the author of 3 books and over 200 professional papers, including papers on measurement error modeling, regression variance functions and transformations, nutrition, toxicology, and bioinformatics. Dr. Carroll received his Ph.D. in Statistics from Purdue University in 1974.
James Hardin is Lecturer and Assistant Research Scientist at Texas A&M University and previously was a Senior Statistician at StataCorp, where he developed Stata's cross-sectional time-series capabilities. He is also the author of Stata's current GLM command. He is the author of two books and ten refereed papers, and he has recently been working with Henrik Schmiediche, developing the software, in Stata, for the estimation of measurement-error models. Dr. Hardin received his Ph.D. in Statistics from Texas A&M University in 1992.
