ASA COLORADO-WYOMING CHAPTER WINTER MEETING

DATA VISUALIZATION, META-ANALYSIS AND BAYESIAN METHODS IN
MEDICINE AND EPIDEMIOLOGY: DRAFT PROGRAM


A ONE-DAY SYMPOSIUM ORGANIZED BY THE DEPARTMENT OF STATISTICS
AT COLORADO STATE UNIVERSITY AND THE DEPARTMENT OF MATHEMATICS AT
CU-DENVER

19 JANUARY 1996

9.30 AM - 5.00 PM

ROOM 640,

TIVOLI BUILDING

AURORIA CAMPUS

CU-DENVER
   

The use of meta-analysis (the formal evaluation of multiple study
information) is
exploding, both in clinical study assessment and epidemiology. This
seminar
will present a
number of areas of this methodology and related subjects, and in
particular will focus on:


* Graphical presentation of both spatial distribution and
meta-analytic results  of multiple studies

* Random effects and Bayesian methods for meta-analysis

* Assessment of publication bias and quality levels in studies

 

Cost of the symposium is  $20 for non-students and the ASA Chapter will
fund attendance of students: this will cover costs of rooms and of
morning and afternoon refreshments.
