In 1825, Benjamin Gompertz proposed a mathematical model for time series that looks like an “S-curve”.1  Mathematically it is a double exponential (Figure 1) where y=a(exp(b(exp(-ct)))) where t is time and a, b and c are adjustable coefficients that modulate the steepness of the S-Curve.  The Gompertz Curve has been used for a … Read More
