Abstract
General treatment for unfolding particle size distributions in a 3-dimensional specimen is possible if the particles spacial distribution, the sampling method, and the observational method are described by probabilistic models. Particles -within “k” discrete groups are sized -with a single characteristic dimension (e.g., diameters for spheres). The spacial distribution of particle centers is assumed uniform. The sample consists of all particles intersected by a probe. AFi/τ is the intersection probability for an ith size particle, with A the characteristic dimension of the probe and τ the specimen volume. The observations of sampled particles are sized into c cells. Pji is the conditional probability that an ith size particle is in the jth cell. The number of observations in the jth cell is mj. The expected values and the covariances of the mi’s are linear functions of the specimen population densities ρ̑i. Population density estimates ρi, and their covariances follow from the Gauss-Markov Theorem.
