Description
Matches MAF distribution of independent set of SNPs to MAF distribution of whole set of SNPs to avoid MAF-based confounding.
Usage
match_ind_maf(maf, indep_index)
Arguments
maf
minor allele frequencies of (all) SNPs
indep_index
indices of independent SNPs
Value
indices of independent SNP in chosen in sample
Details
Must supply maf values from the whole data set, not just the independent SNPs.
