Comparison of multi-trait GWAS methods.

1.5 million variants were simulated with z-scores for four traits with 10% of variants as truly associated. The first column lists which trait has a genetic effect. The second column is the number of variants simulated under this specific model. The third column is the genetic effect size. The remaining four columns contain the number of variants identified as associated by four methods: PAT, HIPO, MTAG, and ASSET. The final row of the table contains each methods running time.
