A least-squares approach was used to fit diameter growth with the logistic curve for each genotype.
He studied the Verhulst equation and the logistic curve.
In evolutionary biology, a question of how a population evolves on a logistic curve is determined by how selection acts on the growth and by the local geometry of the curve itself.
