Abstract

Resumen:Este artículo se refiere a la aplicación de la curva logística, que es un instrumento matemático usado por biólogos y demografistas para describir el crecimiento de poblaciones animales y de poblaciones humanas, así como para formular pronósticos futuros, a los censos de la ciudad de Medellín - Colombia, efectuados entre 1912 y 2005. Presentamos aquí la aplicación del método para calcular la curva logística de una población a partir de recuentos anteriores, y usando la técnica de mínimos cuadrados, desarrollada por Gabriel Poveda Ramos en la referencia [1]. La parte numérica del proceso se ilustra de una manera simple para un mejor entendimiento del manejo de esta técnica que, aunque es muy conocida y sencilla de usar, hasta hoy no se ha empleado (que sepamos) para ajustar dicha curva.Abstract:This paper refers to the logistic curve application which is a mathematical tool often used by biologists and demographers to describe the growth of animal and human populations, as well as to make forecastings on that growth to the censuses realized in Medellín- Colombia city, between 1912 and 2005. Here is presented this method in order to calculate the logistic curve for a given population on the basis of previous censuses, and using the technique of minimum squares, developed by Gabriel Poveda Ramos in reference [1]. The numerical part of the process is simply illustrated for better understanding of this technique that is well known and easy to use but, it has not been employed heretofore to adjust the logistic curve.
