摘要：
With data from line transect surveys, the pattern of distances at which animals [wildlife] are detected provides the information for estimating the area which the observer effectively surveys. A parametric structure is suggested for the problem in which this area is characterized by an effective 1/2 width parameter which appears as a scale parameter in the distributions of detection distances. Suggestions for classes of models are given, different members of a class giving different shapes to the distributions. Examples are discussed.
