Uh .. what are the functions plotted here?

Could the author please supply the expressions that were plotted here? They don't seem to match those used in the en logistic distribution article, as far as I can tell ...

Maybe I'm being really silly here; in any case, the expressions should be in the image description no matter what.

Thanks

Standard Logistic Distribution Function

Standard Logistic distribution Function is Calculated as:

f(x)=1/(1+exp(-x))

Is there a generalized version of it?--Tarawneh 22:24, 18 June 2006 (UTC)

Yes, but not significantly so: you can shift the expression you gave, and you can scale it, so the general formula for the cumulative distribution function is

${\frac {1}{1+e^{-(x-\mu )/s}}}\!$ (from en:)

Found it. General Function with Five parametrs, with the Logistic Distribution Function as a special case [1] --Tarawneh 23:59, 19 June 2006 (UTC)
