Description Objects from the Class Slots Methods Author(s) Examples


Objects of class /probab/ gives the possibility to store in a standardized way, important pieces of information about a probability distribution: the family, the support, and possibly the truncation interval. This a basic object not to be handle by end-users. Notice that no slot is devoted to the name of the described node. It is used in /distri/ and /nod/ objects.
