Providing Intuition to the Fieller Method with Two Geometric Representations using STATA and Eviews

The Fieller Method for the construction of confidence intervals for ratios of the expected value of two normally distributed random variables has been shown by a number of authors to be a superior method to the delta approximation. However, it is not widely used due in part, to the tendency to present the intervals only in a formula context. In addition, potential users have been deterred by the potential difficulty in interpreting non-finite confidence intervals when the confidence level is less than 100%. In this paper we present two graphical methods which can be easily constructed using two widely used statistical software packages (Eviews and Stata) for the representation of the Fieller intervals. An application is presented to assess the results of a model of the non-accelerating inflation rate of unemployment (NAIRU).Fieller method, ratios of parameters, confidence interval, confidence ellipsoid,1st derivative function, NAIRU, EViews, STATA

Two geometric representations of confidence intervals for ratios of linear combinations of regression parameters: An application to the NAIRU

We present two geometric representations of the Fieller confidence interval for the ratio of regression parameter estimates using standard statistics packages. These methods are used to interpret the estimation of the NAIRU for Australia.Fieller Method Confidence ellipse 1st derivative function Eviews Stata

Système spectrométrique interférentiel proposé pour l'Université de Wisconsin

The proposed device may include any number of gratings and Fabry-Perot etalons. The spectrum is scanned by varying the pressure. Perfect synchronism in the scanning of each element (grating or Fabry-Perot) is obtained simply by putting them all together in the same variable pressure chamber.Le dispositif proposé peut comprendre un ou plusieurs réseaux et un ou plusieurs Fabry-Perot. L'exploration du spectre est obtenue par variation de pression. Un synchronisme rigoureux entre les explorations pour les différents éléments (réseaux ou Fabry-Perot) est assuré simplement en les enfermant dans la même enceinte où l'on effectue la variation de pression
