Figure 1From: Detecting single-nucleotide polymorphism by single-nucleotide polymorphism interactions in rheumatoid arthritis using a two-step approach with machine learning and a Bayesian threshold least absolute shrinkage and selection operator (LASSO) modelMajor effects and interaction basis functions detected by the Bayesian threshold LASSO model. Allele or interaction alleles are specified. The allele for the HLA SNPs is specified first in the interactions.Back to article page
