Young Statisticians Session:
Dealing with missing data in quality of life outcomes
Discussed are the results of a review of a random selection of RCTs
published during 2005/6 in a variety of medical journals to assess the
extent of use of imputation. A particular RCT will be used to illustrate
issues involved in identifying the missing data mechanism and suitable
simple imputation methods
Ian White (MRC Biostatistics Unit, Cambridge)
Informatively missing data in randomised controlled trials
In RCTs assumption about missing data mechanisms are made; particularly
missing at random. Such assumptions are rarely entirely plausible.
Sensitivity analysis and Bayesian analyses are described to use the
knowledge of richer data to estimate the missing data mechanism. Also
discussed is the sort of analysis with missing outcomes that deserves the
title intention-to-treat.
Cheti Nicoletti (with Franco Peracchi and Francesca Foliano)
(Institute for Social and Economic Research, University of Essex)
Estimating income poverty in the presence of measurement error and missing
data problem
Reliable income poverty indicators based on survey data are plagued by
measurement errors and missing data. Using the European Community Household
Panel, bounds for poverty rates in eleven European countries are developed
using upper limits on the probability of misclassifying people into poor
and non-poor. These are subjected to sensitivity analysis.
Nicky Best (Epidemiology and Public Health, Imperial College)
Bayesian graphical models for imputing missing outcomes and confounders in
administrative databases: application to an analysis of low birthweight and
water disinfection byproducts
ALL ARE WELCOME. THERE IS NO CHARGE
