          Abstract

          Se introducen las conocidas curvas ROC (relative operating characteristic) y sus medidas de detectatibilidad asociadas, para la validación de varios predictores del rendimiento académico. Se hace énfasis en las ventajas de este instrumento sobre otras medidas clásicas conocidas como la sensibilidad y la especificidad, para comparar la efectividad de diferentes variables con fines pronósticos. Se exponen algunos resultados relacionados con el fundamento, la interpretación y las expresiones para el cálculo de las diferentes medidas de detectabilidad y se ilustra la aplicación de estas medidas para mostrar las ventajas del índice académico sobre las pruebas de ortografía en el pronóstico del aprovechamiento docente en la enseñanza médica superior.

          Translated abstract

          The well-know ROC curves (relative operating characteristic) and their associated detectability measures, are introdced for the validation of several predictors of the academic achievement. Emphasis is made on the advantages of this instrument over other know classic measures, as sensitivity and specificity, to compare the effectiveness of several variables with prognostic purposes. Several results related with the foundation, interpretation and expressions for calculating the different detectability measures, are exposed, and the application of these measures is illustrated, to show the advantages of the academic index over the orthography tests in the prognostic of the educational achievement in the superior medical education.

              ROC analysis applied to the evaluation of medical imaging techniques.

              J Swets (2015)
              Analysis in terms of the relative operating characteristic (ROC) has recently been applied to several studies of medical decision-making, primarily to decisions based on imaging techniques. This paper presents a brief description of the ROC, and shows how it provides a measure of diagnostic accuracy that is free of judgmental bias. The results of medical studies are reviewed, and the main questions of theory and method that have arisen in the medical context are identified. Certain of these questions are basic to any psychophysical test, in which case an attempt has been made to present the best available answers. Other questions are of special medical importance and relevant reports are reviewed along with a description of current efforts to provide answers.
