Likelihood for CKMR

Returns the log-likelihood for a set of pairwise comparisons. For a parent-offspring pair, a comparison is defined by the capture year of parent, capture age of parent, and birth year of offspring. For a half-sibling pair, a comparison is defined by the cohort year of each sibling. Binomial and Poisson distributions are supported (Conn et al. 2020).

Usage

like_CKMR(n, m, p, type = c("binomial", "poisson"))

Arguments

n

The number of pairwise comparisons

m

The number of kinship matches

p

The probability of kinship match

type

The statistical distribution for the likelihood calculation

Value

Numeric representing the log-likelihood.
