A variable undergoing logistic growth initially grows exponentially. After some time, the rate of growth decreases and the function levels off, forming a sigmoid, or s-shaped curve. For example, an ...

Especially in the logistic function, the growth rate of a tumor cell population without competition can be explicitly defined by a parameter of net growth. As we have previously estimated the net ...

Several models have been proposed to describe germination rates, but most are limited in statistical analysis and biological meaning of indices. Therefore, a mathematical model is proposed to utilize ...

A reparametrization of the two-parameter logistic growth function is given which, for independent homoscedastic normally distributed error terms, yields maximum ...
