Figure 1From: Case-control genome-wide association study of rheumatoid arthritis from Genetic Analysis Workshop 16 using penalized orthogonal-components regression-linear discriminant analysisSNPs identified using POCRE-LDA. The x-axis indicates the physical location of each SNP on the chromosome, and the y-axis represents the absolute value of the estimated coefficient, i.e., |b j |. Genetic regions with multiple SNPs are identified in chromosomes 6, 8, 9, 10, and 18.Back to article page
