Please join us for another exciting talk in the CCASA's 2009-2010 Luncheon program!
Our March speaker is Juned Siddique, DrPH, Assistant Professor at Northwestern University's Feinberg School of Medicine, who will be speaking about Analytical Issues with Missing Data in Longitudinal Trials.
Longitudinal designs have many benefits, including the ability to measure the course of a disease over time. However, measuring participants repeatedly over time also leads to repeated opportunities for missing data, either through failure to answer certain items, missed assessments, or permanent withdrawal from the study. To avoid bias and loss of information, one should take missing values into account in the analysis. Several popular ways that are now being used to handle missing data, such as the last observation carried forward (LOCF), often lead to incorrect analyses. We discuss a number of these popular but unprincipled methods and describe modern approaches to classifying and analyzing data with missing values. We illustrate these approaches using data from the WECare study, a longitudinal randomized treatment study of low income women with depression.
Lunch is $30 for CCASA members, $35 for non-members. Non-members, join the chapter for a year for only $15 and get the discount plus all of the other benefits of membership!
