Calculate the conditional probability of observing a carcass at search oi as a function arrival interval (assuming carcass is not removed by scavengers before the time of the final search)
SEsi_left(oi, pk, rng = NULL)
number of searches after arrival
numeric array of searcher efficiency p and k parameters (p = pk[ , 1] and k = pk[ , 2])
optional parameter giving the range of intervals to consider
numeric array of probability of observing a carcass at oi for
given that it arrived in intervals 1:oi if rng = NULL (or in intervals
rng
), assuming the carcass had not been previously discovered or
removed by scavengers
