adm_estimates: Ancestry-specific allele frequency estimates for 56,003...

Description Usage Format Author(s) Source References


Ancestry-specific allele frequency estimates computed by applying ASAFE's EM algorithm to simulated unphased genotypes (ignoring phase information from simulated phased genotypes) and simulated phased ancestries.




A 56,003 x 4 matrix with the following rows, columns, and entries:

  1. Rows: 1 row per bi-allelic marker, with alleles arbitrarily labeled 0 and 1

  2. Columns: Marker ID, followed by ancestries 0, 1, and then 2

  3. Entries: The (i,j)-th entry when j is a column corresponding to an ancestry, gives the estimated frequency of allele 1 amongst admixed chromosomes of that ancestral origin at the i-th marker.

This is the result of applying ASAFE functions to simulated genotype and ancestry data. See ASAFE vignette for details.
