A polar confidence curve applied to Fiellerís ratios
Abstract: I derive the polar representation of Fieller's estimation
of confidence sets for ratios and construct a polar plot of the test
statistics for all angles associated with the ratios. This procedure helps
in visualizing and clarifying, but also systematizing, the features of the
Fieller solution. In conclusion I discuss, using Ramanujan, the case where
Fieller's method yields a confidence set covering the entire real line.
