Abstract: A method of determining the weight distribution of a population is provided, including the steps of a) determining a likely weight range for members within the population; b) enabling a plurality of members of the population to impact on a weighing device wherein multiple members may be on the weighing device at one time; c) recording inputs from the weighing device wherein each input corresponds to the presence of the multiple members on the weighing device at one time; and d) using values derived from the inputs and applying an algorithm to specify a number of subsets, each of the subsets representing a discrete number or proportion of members with weight values associated with same.

Abstract: A method of measuring a biological process, the method including the steps of: (a) determining a probability density function for a series of repeated measurements of the biological process; (b) approximating the probability density function utilising a parametric formula; (c) determining a maximum likelihood estimator for the parametric formulation of the probability density function; and (d) utilising the maximum likelihood estimator for subsequent measurements of the biological process.
