This article will cover the basic theory behind logistic regression, the types of logistic regression, when to use them and take you through a worked example.

The slope of the curve at any given time is the intrinsic rate of population growth. As growth rate is a function of both N and K, growth slows as density of the population approaches carrying ...

How to Plot Logistic Growth in Excel. A variable undergoing logistic growth initially grows exponentially. After some time, the rate of growth decreases and the function levels off, forming a ...
