Pedigree-based Relatedness Coefficients

Recursive algorithms for computing various relatedness coefficients, including pairwise kinship, kappa and identity coefficients. Both autosomal and X-linked coefficients are computed. Founders are allowed to be inbred, enabling construction of any given kappa coefficients (Vigeland (2020) ). In addition to the standard pairwise coefficients, ribd also computes a range of lesser-known coefficients, including generalised kinship coefficients (Karigl (1981) ; Weeks and Lange (1988) ), two-locus coefficients (Thompson (1988) ) and multi-person coefficients. This package is part of the ped suite, a collection of packages for pedigree analysis in R.
