- Wenting Ye, Xiang Liu, Haohan Wang, E. Xing. 2017. A Sparse Graph-Structured Lasso Mixed Model for Genetic Association with Confounding Correction. Abstract: While linear mixed model (LMM) has shown a competitive performance in correcting spurious associations raised by population stratification, family structures, and cryptic relatedness, more challenges are still to be addressed regarding the complex structure of genotypic and phenotypic data. For example, geneticists have discovered that some clusters of phenotypes are more co-expressed than others. Hence, a joint analysis that can utilize such relatedness information in a heterogeneous data set is crucial for genetic modeling.
