The Gompertz curve is a limiting case of the generalised logistic as T becomes very small or very large.

Y = A + C exp(-exp(-B(X-M)))

where Y=weight, height, size etc; X = time.

A = the lower asymptote;
C = the upper asymptote;
M = the time of maximum growth;
B = the growth rate.

Investigate the Gompertz curve.
