Abstract
We present a new statistical test of association between a trait and genetic markers, which we
theoretically and practically prove to be robust to arbitrarily complex population structure.
The statistical test involves a set of parameters that can be directly estimated from large-scale
genotyping data, such as those measured in genome-wide associations studies. We also derive
a new set of methodologies, called a genotype-conditional association test, shown to provide
accurate association tests in populations with complex structures, manifested in both the
genetic and non-genetic contributions to the trait. Our proposed framework provides a
substantially different approach to the problem from existing methods.
