class logistic_gen(momtype = 1, a = None, b = None, xtol = 1e-14, badvalue = None, name = None, longname = None, shapes = None, seed = None)

A logistic (or Sech-squared) continuous random variable.

%(before_notes)s

The probability density function for logistic is:

f (x) = \frac{exp ( - x )}{( 1 + exp ( - x ) ) ^{2}}

logistic is a special case of genlogistic with c=1.

Remark that the survival function (logistic.sf) is equal to the Fermi-Dirac distribution describing fermionic statistics.
