| Popis: | In this paper we consider inference regarding the ratio of two normal and the ratio of two t-distributed random variables, using both the popular Fieller interval, as well as, exact distributions. We apply these methods to a historical dataset regarding the shape of the Earth, and estimate the Earth's flatness coefficient as a ratio of regression coefficients. We demonstrate the equivalence of the inference using the exact density of this ratio with that using the Fieller interval. |
