A Reinterpretation of Interactions in Regressions

Hirschberg, J.; Lye, J. - Department of Economics, Faculty of Business and Economics - 2007

Regression specifications in applied econometrics frequently employ regressors that are defined as the product of two other regressors to form an interaction. Unfortunately, the interpretation of the results of these models is not as straight forward as in the linear case. In this paper, we...

Interactions in Regressions

Hirschberg, J.; Lye, J. - Department of Economics, Faculty of Business and Economics - 2005

Regression specifications frequently employ regressors that are defined as the product of two other regressors to form an interaction. Unfortunately, these models have a number of potential difficulties when it comes to interpretation. In this paper, we discuss two common aspects of these...

Inferences for the Extremum of Quadratic Regression Models

Hirschberg, Joseph G.; Lye, Jenny N. - Department of Economics, Faculty of Business and Economics - 2004

Quadratic functions are often used in regression to infer the existence of an extremum in a relationship although tests of the location of the extremum are rarely performed. We investigate the construction of the following confidence intervals: Delta, Fieller, estimated first derivative,...

On the equivalence of the net benefit and the Fieller's methods for statistical inference in cost-effectiveness analysis

Zethraeus, Niklas; Löthgren, Mickael - Economics Institute for Research (SIR), … - 2000

This paper shows that there exists a close relation between the net benefit and Fieller's methods for calculation of confidence intervals and performing hypothesis testing in cost-effectiveness analysis. The prices at which the net benefit confidence interval limits are equal to zero are...

How Uncertain are NAIRU Estimates in Colombia

Julio, Juan Manuel - Banco de la Republica de Colombia

Most of the proposed macro models and Phillips curves for policy design and analysis in Colombia depend on estimates of the potential output. However, it is widely known that this estimates are highly unreliable because of its level of estimation uncertainty. Following Staiger et al.(1996), we...
