A generalization of the common logistic function is developed, incorporating a non-unit saturation level, a non-zero intercept, and a non-symmetric shape. The dependence of the three generalized ...

A method is described for fitting Richards' generalisation of the logistic function by the method of least squares. The solution of the equations obtained requires the use of an iterative process from ...

The LOGISTIC procedure includes several new MODEL statement options that provide additional control over the model-fitting process. The ABSFCONV= option specifies the absolute function convergence ...

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.

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 ...
