Two very different types of correlation ore examined. First, the problem of correlating two different toxic potentials, such as mutageneais and carcinogenesie, over a class of chemicals is discussed and shown to be quite difficult unleas strong assumptions are made about the dose-response curves for each effect. The second type of correlation is that of joint occurrences of symptoms over a population of 8ubjecta.A latent class model whose parametem are h e i r functions of dosage is proposed based on a two-stage theory of carcinogeneais. This model S U ~~I M E E E various alternative models in predicting multiple site tumors resulting from exposure to the solvent l,%-bntadiene.

This paper discusses the use of frequency}domain criteria for "nite element (FE) model correlation and updating. The criteria, which can be local or global, are either shape or amplitude based. The former are sensitive to mode shape di!erences but not to relative scales, and the latter depend on the
