If you have Java enabled on this browser, you can experiment with various settings of the parameters of a generalized logistic curve and see the results plotted in the diagram below.

For comparison purposes the curve for the previous setting of the parameter is plotted in red while the current setting is in blue . The formula for the curve is : Y = A + C/((1 + T exp(-B(x-M))) ^ (1/T))

Applet

You can investigate the Gompertz curve by setting the T parameter in the Generalised Logistic to 0.5 first and then to 90.
