Abstract

ALONSO, Julio César  and  GALLO, Beatriz Eugenia. The problem of the consultancy is in the t. estud.gerenc. [online]. 2013, vol.29, n.126, pp.118-124. ISSN 0123-5923.

This case of study aims to strengthen the ability of the reader to systematically solve issues that involve using econometric tools. We focus on the linear regression model. The problem is about the estimation of a demand curve, which leads to hypothesis testing for a linear regression model. The discussion deals with a problem that seems to be taken for granted, and it also mentions the importance of considering theoretical implications when using one- and two- tailed tests.

Keywords : Linear Regression Model; t-test; Model comparison; Demand estimation.
