Estimating absence

The problem addressed is absence of a class of objects in a finite set of objects, which
is investigated by considering absence of a species and absence in relation to a threshold.
Regarding absence of a species, we demonstrate that the assessed probability of absence
of the class of objects in the finite set of objects given absence of the class in the sample
is either exactly or approximately equal to the probability of observing a specific single
object from the class of objects given the protocol for observation, where probability is
interpreted as a degree of belief. Regarding absence in relation to a threshold, we
develop a new estimator of the upper confidence bound for the finite population
distribution function evaluated at the threshold and investigate its properties for a set of
finite populations. In addition we show that estimation regarding the initial ordered value
in the finite population has limited usefulness. / Graduation date: 1998
