Performance of DPR and PrediXcan with Respect to Various Training Sample Sizes

Test R² (A) and TWAS power (B) from simulation studies with causal proportion p_causal = 0.2, expression heritability and phenotype heritability $\left({\text{h}}_{\text{e}}^2,{\text{h}}_{\text{p}}^2\right)=\left(0.2,0.25\right),$ and various training sample sizes (100, 300, 499).
