On The Performance of the Logistic-Growth Population Projection Models

Abstract

In this paper, we proposed two mathematical Models for population projection, the exponential growth and the Logistic Model. Thereafter, both Models were transformed and since Logistic Model is not linear in its parameters hence a surgery was performed on the data values separated by a fixed time say This enables the Logistic parameters to be sometimes estimated by Least-Squares. It was shown that the estimates ? ? ? were quite close to the data set from the National Population Commission of Nigeria.Keywords: Carrying capacity, Logistic Model, Exponential growth, Polyfit, Least- Squares, Population Projection.
