Summary
Individuals who live near each other tend to be more similar genetically than individuals who live in different parts of the world. One reason is that they share more of their genetic ancestry. There can be very subtle differences in patterns of genetic variation even within countries. Accounting for these subtle differences can be important for studies of the genetic basis of diseases. We will develop novel statistical methods to control for these genetic differences in disease studies.

Summary
Missing data arise in most research studies and if not handled appropriately can mean the study results are not correct. With researchers now conducting larger and longer studies the challenges posed by missing data are increasing. In this grant we study a powerful technique for handling missing data, which in its current form often cannot be applied effectively in large studies. By developing this approach we will improve the accuracy of results from large-scale epidemiological studies.
