Abstract

El objetivo de este caso es reforzar la capacidad del lector de aproximarse de forma sistémica a un problema que requiere el uso de herramientas econométricas, en especial la regresión múltiple. Para ello, el problema se contextualiza en una empresa consultora que debe estimar una función de demanda y debe determinar qué pruebas de hipótesis deben hacerse para los coeficientes del modelo de regresión lineal estimado. Esta discusión toca un tema que parece darse por sentado, pero que refleja la necesidad de reflexionar acerca de las razones por las cuales se hace uso de una prueba t individual de 2 colas o de 1 cola y la relación con la teoría económica.
