:We still have to figure out about what REAL equation is in the background. It's not relativity, entropy, or thermodynamics. But the picture looks familiar to me, my poor old brain just do not remember.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 18:47, 22 July 2013 (UTC) | :We still have to figure out about what REAL equation is in the background.

::The first factor alone would describe a shifted {{w|exponential decay}}. The second factor is a scaled and shifted {{w|sigmoid function}}, more precisely the hyperbolic tangent shifted to have its inflection at ''(k<sub>2</sub>,0.5)'' and vertically scaled by ''d''. I'm not sure if that helps anyone, though ... --[[User:Chtz|Chtz]] ([[User talk:Chtz|talk]]) 08:40, 23 July 2013 (UTC) | ::The first factor alone would describe a shifted {{w|exponential decay}}.
