Overview
This lecture introduces the problem of population stratification in the context of genetic association studies. It also discusses three possible strategies for handling population structure, specifically:
- Using family based association tests, such as the TDT.
- Controling the overall inflation of test statistics, using the genomic control method.
- Using genotype based matching approaches.
