Webb24 mars 2024 · Not sure, but looks like Plink doesn't do that (you can simulate phenotype as long as you also simulate the genetic data as well...) PS 1: I managed to simulate it before as answered here , but I've just realised it doesn't generate reliable ratios (although the logic in place, phenotypes are still too aleatory assigned - too low precision, recall … Webb8 apr. 2024 · Next, we varied the additive heritability, which affects the EO test power because it governs the accuracy of the PRS estimates (SI Appendix, Fig. S3B). As expected, power increased with heritability, growing from 35% at h 2 = 0.1 to nearly 100% at h 2 = 0.7 (our baseline is h 2 = 0.5). Finally, we varied the strength of CE parameter, γ.
