Method for determining the distribution of constituent subpopulations within a population of particles having overlapping subpopulations

摘要

A method and apparatus for determining the parameters (i.e., proportion, mean, and standard deviation) of constituent subpopulations within a sample population of particles which contains overlapping populations. The invention includes the use of the EM algorithm, an iterative process which estimates the probability that a particle belongs to any given overlapping subpopulation.
