Missing data (3.12.2012 ob 14.00 - 17.00)

The first part of the lecture will cover the basic concept of missing data, what constitutes missing data, patterns of missingness, and naive ways to deal with the problem of missing data. We will then consider reasons for missingness and the classification of these reasons into MCAR, MAR, and MNAR mechanisms. We will continue with a discussion of principled methods to address missingness, primarily maximum likelihood, usually implemented by EM, and Bayesian, usually implemented by MCMC as well as multiple imputation methods. Further, we will address why it is important to investigate the sensitivity of statistical conclusions to assumptions about the missingness mechanism. The second part of the lecture will present methods for displaying the sensitivity of statistical conclusions to these reasons with the use of graphical methods that rely on modern computing, in particular, a new method called “enhanced tipping point displays”.
