In ddalthorp/GenEst: Generalized Mortality Estimator

Calculate the negative log-likelihood of a searcher efficiency model

Description

The function used to calculate the negative-loglikelihood of a given searcher efficiency model (pkm) with a given data set

Usage

pkLogLik(
  misses,
  foundOn,
  beta,
  nbeta_p,
  cellByCarc,
  maxmisses,
  cellMM,
  kFixed = NULL
)

Arguments

misses	Number of searches when carcass was present but not found.
foundOn	Search on which carcass was found.
beta	Parameters to be optimized.
nbeta_p	Number of parameters associated with p.
cellByCarc	Which cell each observation belongs to.
maxmisses	Maximum possible number of misses for a carcass.
cellMM	Combined pk model matrix.
kFixed	Value of k if fixed.

Value

Negative log likelihood of the observations, given the parameters.
