> Something is wrong or unclear...
> We read:

> "Parametric function where the input array contains the parameters
> of the logit function, ordered as follows: "
> --> But the "logit" function is not the "logistic" function.
> http://commons.apache.org/proper/commons-math/apidocs/org/apache/commons/math3/analysis/function/Sigmoid.Parametric.html
> "Parametric function where the input array contains the parameters of
> the logit function, ordered as follows: "
> --> But the "logit" function is not the "sigmoid" function, and what is
> the difference between the Logistic Function snd the Sigmoid function?
> http://commons.apache.org/proper/commons-math/apidocs/org/apache/commons/math3/analysis/function/Logit.Parametric.html
> "Parametric function where the input array contains the parameters of
