1. List three distinct models that
Grandjean et al. (1998) employ in the attached paper on
methylmercury exposure and cognitive ability.
For (i) each model, state
(ii) what it represents (that is, what is it a surrogate of),
state (iii) whether it is a physical, abstract and/or sampling
model (That is, what type of model is it?), and
(iv) state a key assumption inherent in Fingerhut et al.’s
use of this model. Finally, (v) briefly describe the
status of each model. To describe the model status,
observe that for some but not all models you may
find it helpful to employ the terminology: accept,
reject, consistent, inconsistent, support, refute.
