The Current and Future Use of Ridge Regression for Prediction in Quantitative Genetics

Figure 6

The predicted logarithm of the ratio of the attained by ridge regression and the classical GWAS approach of RSR, based on a model fitted to this measure in 21 runs of simulations. Predictions are shown for different combinations of training sample size (-axis), number of SNPs (-axis), trait heritability (-axis in the subplots), and fraction of SNPs with a causal effect (-axis in the subplots). Predicted values are not truncated. Deep green represents the highest prediction.
