Several machine learning methods, including sparsity-promoting regularization methods (SRMs), such as Lasso7, Elastic Net (EN)8, Adaptive Lasso (AL)9and sparse group Lasso (SGL)10, provide predictive modeling frameworks adapted top ≫ nomic datasets. Furthermore, data fusion methods, such ...
with smaller gains from algorithmic improvements. We find that LASSO generally performs as well as the best methods, judged by a variety of metrics. We also investigate performance characteristics of predictors trained on one genetic ancestry group when applied to another. Using LASSO, we develop a...
