Score Details

Score Construction
PGS Name logTG_AFR_ldpred2
Development Method
Name ldpred2
Parameters Default parameter setting in bigsnpr version 1.12 -- the proportion of causal SNPs is chosen from a sequence of length 17 that are evenly spaced on a logarithmic scale from 10^(-4) to 1; per-SNP heritability is chosen from 0.7, 1, or 1.4 times the total heritability estimated by LD score regression divided by the number of causal SNPs. "sparse” option = to FALSE.

Performance Metrics

Disclaimer: The performance metrics are displayed as reported by the source studies. It is important to note that metrics are not necessarily comparable with each other. For example, metrics depend on the sample characteristics (described by the PGS Catalog Sample Set [PSS] ID), phenotyping, and statistical modelling. Please refer to the source publication for additional guidance on performance.
