The Component Logistic Model

As it turns out, many growth and diffusion processes are actually made up of several subprocesses. First, let us consider the case of a system which experiences growth in two discrete growth phases. Then, we will extend this to an arbitrary number of phases.

Systems with two growth phases follow what we call the ``**Bi-logistic''** model [12]. In this model, growth is the sum
of two discrete ``wavelets''
, each of which is a three-parameter logistic:

where

Naturally, we can examine system-level behavior (i.e.,
