pkLogLik

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

Command-line and 'shiny' GUI implementation of the GenEst models for estimating bird and bat mortality at wind and solar power facilities, following Dalthorp, et al. (2018) <doi:10.3133/tm7A2>.
