Fig 1. A comparison of R2 between prediction and measurement in SAGE, with PredictDB test metrics as benchmarks, for 11,545 genes total.
The prediction weights used here are, from left to right: GTEx v6p, GTEx v7, DGN, MESA African Americans, MESA African Americans and Hispanics, MESA Caucasians, and all MESA subjects. Test R2 from model training in GTEx 7 and MESA (“test_R2_avg” in PredictDB) appear on the right and provide a performance baseline. The number of genes per weight set varies; see S1 Table.
