# Growth Curves for a Mixture of Two Subpopulations

Growth Curves for a Mixture of Two Subpopulations

The growth curves of two-subpopulation mixtures can have shapes that are practically indistinguishable from those of a homogeneous population, but they can also have a variety of distinctly different shapes. This is shown with simulated growth curves generated with a double-stretched exponential model and a two-term non-exponential model. The Demonstration also shows how a minor change in one of the subpopulation's growth parameters can sometimes result in a major change in the shape of the mixture's growth curve.
