Generalised Logistic Function

Generalised Logistic Function

The generalised logistic curve or function, also known as Richards' curve is a widely-used and flexible sigmoid function for growth modelling, extending the well-known logistic curve.

where Y = weight, height, size etc., and t = time.

It has six parameters:

  • A: the lower asymptote;
  • K: the upper asymptote. If A=0 then K is called the carrying capacity;
  • B: the growth rate;
  • ν>0 : affects near which asymptote maximum growth occurs.
  • Q: depends on the value Y(0)
  • M: the time of maximum growth if Q

    To make us feel small in the right way is a function of art; men can only make us feel small in the wrong way.
