Abstract:
While most statistics and biostatistics teaching programs focus almost exclusively on additive models and sums and differences of parameters, biostatistics practioners have to deal with multiplicative models and the (interval) estimation of ratios of parameters. This talk will point possible problems and weaknesses of the usual approach of log transformation (of ratios) as well as to explore possible remedies. Examples cover a wide range of applications (epidemiology, bioassays, diagnostic tests, clinical trials).

A social tea will be held at 3:00 P.M. in A434 Mayo. All are Welcome.
