Eigendecomposition-Based LD Statistic

Pre-computed per-block eigendecompositions of the LD correlation matrix. Used by LDER, HDL, and sHDL.

Slots

eigen_list

A list of length n_blocks, each element a list with components:

values

Numeric vector of eigenvalues

vectors

Numeric matrix of eigenvectors (SNPs x retained components)

snp_idx

Integer vector of SNP indices in snp_info

eigenvalue_truncation

Numeric, proportion of variance retained (e.g., 0.9 for HDL's default). If 1.0, no truncation.
