Abstract

Analysis of data on weight frequency particle size distributions involves at least three main problems: (i) choosing a physically realistic theoretical frequency function for the distribution, (ii) determining adequate criteria of fitting a chosen model, and (iii) assessing the sampling error in the summary statistics extracted by the chosen model from the data. The present paper highlights the existing theory that a minimum distance criterion can be readily applied in fitting a chosen model and provides discussion on choice of models for a particular problem at hand by means of an example in the science of shear-flocculation. An application of the criterion and an illustration on the choice of models is provided by a specific particle size data set that arose in shear-flocculation of scheelite suspension.
