Abstract
The parameter-effects curvature measure proposed by Bates and Watts (1980) is examined for a growth model and the Fieller-Creasy problem. Exact confidence regions are constructed and compared to linear approximation regions. For the growth model the agreement between the regions is good despite high curvature. In the Fieller—Creasy problem it is shown that the agreement can be quite poor despite low curvature.Keywords
