Fitzmaurice (School of Public Health, Harvard University)

Wednesday December 11 at noon
Center for Basic Research in the Social Sciences
34 Kirkland Street, Room 22
Lunch will be served.

 Abstract: In this talk we give an introduction to two common approaches
 to handling nonignorable dropout in longitudinal clinical trials
 based on selection and pattern mixture models.
 Some of the distinct advantages and disadvantages of selection
 and pattern mixture models are reviewed and highlighted.
 An example, based on data from a clinical trial of contracepting
 women, is used to illustrate some of the main ideas.

There is no paper available, however a related paper by the presenter,
"Methods for Handling Dropouts in Longitudinal Clinical Trials" can be

The Research Workshop in Applied Statistics is a year-long forum for
graduate students, faculty, and visiting scholars to present and discuss
statistical innovations and applications in the social sciences. The
Fitzmaurice talk is the final presentation of the Fall 2002 semester.
The first talk of the Spring 2003 semester, "Enhancing the Validity and
Cross-Cultural Comparability of Survey Research" will be given on January
