See also the description of Logistic.Parametric in http://commons.apache.org/proper/commons-math/apidocs/org/apache/commons/math3/analysis/function/Logistic.html which doesn't match the constructor of "Logistic" at all. > Confused by the API docs for org.apache.commons.math3.analysis.function > ----------------------------------------------------------------------- > > Key: MATH-1022 > URL: https://issues.apache.org/jira/browse/MATH-1022 > Project: Commons Math > Issue Type: Bug > Affects Versions: 3.3 > Reporter: David Tonhofer > > Something is wrong or unclear... > We read: > http://commons.apache.org/proper/commons-math/apidocs/org/apache/commons/math3/analysis/function/Logistic.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 "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 > the logit function, ordered as follows: " > --> That sounds correct. > References: > http://en.wikipedia.org/wiki/Logistic_function > http://en.wikipedia.org/wiki/Logit > http://en.wikipedia.org/wiki/Sigmoid_function -- This message is automatically generated by JIRA.
