Plink effect size
Webb18 feb. 2024 · When the effect and non-effect allele are inverted between datasets then this can be resolved automatically by some software (e.g., PLINK 2) or manually by relabelling the effect and non-effect allele in the PRS summary data, and inverting the effect size accordingly (since the effect size is the additive effect of each copy of the … Webb22 dec. 2024 · Revised on November 17, 2024.
