I'm looking for an S-curve formula for forecasting purposes
J Jerry W. Lewis Oct 23, 2004 #2 More specific requirements would help, since there are any number of S-curves. Every continuous probability distribution is an S-curve, including http://groups.google.com/groups?selm=416A73F3.8070300@no_e-mail.com In bioassay, you frequently see 4-parameter or 5-parameter logistic models http://groups.google.com/groups?selm=402368E1.5000609@no_e-mail.com and that just barely scratches the surface.
