Computes distribution of number of IBS alleles for profiles with stated relationship

Description

Computes, per locus, the distribution of a Kinship Index (KI) comparing hypotheses hyp.1 vs hyp.2 for profiles with a given relationship (hyp.true), optionally with respect to the case profile (e.g. "FS" for full siblings).

Usage

1
2
ibs.dist(x, hyp.true = "UN", freqs = get.freqs(x), markers = names(freqs),
  theta = 0)

Arguments

x

(optional) An integer matrix specifying a single profile.

hyp.true

A character string specifying the true relationship between the two profiles. Forwarded to ibdprobs, e.g. "FS" (full sibling) or "PO" (parent/offspring) or "UN" (unrelated). Defaults to "UN".

freqs

A list specifying the allelic frequencies.

markers

A character vector giving the markers for which the distribution is derived. Default to the markers of freqs.

theta

numeric value specifying the amount of background relatedness.

Value

A list of distributions, where a distribution is specified by a list with vectors x, fx.
