Abstract
En este ensayo se presenta y analiza el coeficiente de correlación, una herramienta estadística elemental e importante para el estudio econométrico de relaciones lineales bivariadas que involucran el uso de datos de corte transversal o series de tiempo. En particular, se analiza el coeficiente de correlación y su relación con las denominadas correlaciones espúreas o sin sentido. Asimismo, se muestran aplicaciones utilizando datos para la economía peruana.
An important statistical tool for the econometric study of linear bivariate relationship that involves the use of cross-section or time series data is presented and analyzed in this essay: the correlation coefficient. In particular, it is analyzed the relationship between the correlation coefficient and spurious or non-sense correlations. Likewise, empirical applications based on Peruvian data are shown.
