To analyze millions of genetic variants, we need tools that are fast and memory efficient. Some of the most efficient tools have problems with numerical instability on dense sets of snps. Bercovich et al. figured out how to overcome a common source of instability: www.biorxiv.org/content/10.1...

LD Matrix Approximations for Scalable Analysis of High-dimensional Genetic Data
Linkage disequilibrium (LD) matrices are an essential part of many statistical genetics methods. However, their high dimensionality makes their computation and storage impractical for large genomic da...
