## Abstract Environmental contamination data frequently follow an extremely right skewed distribution, which is often approximated by a log‐normal distribution. For the purpose of risk assessment it is of interest to use the sample data to calculate an upper bound on the population arithmetic mean.

✦ Synopsis
We consider the problem of estimating a function of the mean vector in multivariate analysis. It is shown that two naive estimators turn out to be biased. Using a generalized jackknife procedure we construct an unbiased estimator of this function as a reasonable alternative. Variances of the three estimators are calculated for the general and the normal case.

We define a new family of matrix means {L μ (ω; A)} μ∈R where ω and A vary over all positive probability vectors in R m and m-tuples of positive definite matrices resp. Each of these means interpolates between the weighted harmonic mean (μ = -∞) and the arithmetic mean of the same weight (μ = ∞) wit
Using several types of simple generating orbitals, explicit expressions for w x w x the kinetic-energy functional T and the exchange functional E were generated in the context of the local-scaling transformation version of density functional theory. The variational parameters in these orbitals were
