Determination of the maximum foregut volume of western rock lobster ( Panulirus cygnus) from field data.

Abstract

Two methods are presented for estimating the parameters of a line that describes the upper boundary of a triangular set of points: 1) a nonparametric maximum likelihood approach in which an unknown mixing distribution is introduced to account for the vertical spread of the points; 2) an iterative modification of the least squares procedure, in which points are weighted according to their distance from a trial line, and thus a new line is obtained; this forms the basis for the next iteration.-from Authors Show more
