DESIGN Retrospective cohort study. SETTING IRF. PARTICIPANTS Two samples of participants (n=110 and 159) ad...

In this paper a method of obtaining smooth analytical estimates of probability densities, radial distribution functions, and potentials of mean force from sampled data in a statistically controlled fashion is presented. The approach is general and can be applied to any density of a single random variable. The method outlined here avoids the use of histograms, which require the specification of ...
