FURTHER RESULTS ON VARIANCES OF LOCAL STEREOLOGICAL ESTIMATORS

Zbyněk Pawlas, Eva B Vedel Jensen

Abstract

In the present paper the statistical properties of local stereological estimators of particle volume are studied. It is shown that the variance of the estimators can be decomposed into the variance due to the local stereological estimation procedure and the variance due to the variability in the particle population. It turns out that these two variance components can be estimated separately, from sectional data. We present further results on the variances that can be used to determine the variance by numerical integration for particular choices of particle shapes.
