The Pritchard-Stephens-Donnelly (PSD) admixture model has k intermediate subpopulations from which n individuals draw their alleles dictated by their individual-specific admixture proportions. The BN-PSD model additionally imposes the Balding-Nichols (BN) allele frequency model to the intermediate populations, which therefore evolved independently from a common ancestral population T with subpopulation-specific FST (Wright's fixation index) parameters. The BN-PSD model can be used to yield complex population structures. Method described in Ochoa and Storey (2021)
Added option noFixed to function rbnpsd to redraw loci that were drawn fixed for a single allele.
These loci are not polymorphic so they would normally not be considered in analyses.
Added function fixed_loci to test for fixed loci within rbnpsd.
coanc_to_kinship to easily obtain kinship matrices from coancestry matrices.
