  1. Confidence intervals for antithmetic means of logonormally distributed exposures.

    Article - En anglais

    Distributions of concentrations of environmental contamiants are often approximately lognormally distributed.

    The arithmetic mean of such distributions is frequently the summary measure most relevant to health.

    Although methods for estimating arithmetic means of lognormal distributions from samples are becoming better known, methods for determining the precision of estimates by confidence intervals are not.
