1Blurb:: 2Assign probability mass to each interval 3Description:: 4The basic probability assignments for each interval variable must sum to one. 5For example, if an interval variable is defined with three intervals, 6the probabilities for these intervals could be 0.2, 0.5, and 0.3 which sum to one, but could not be 0.5,0.5, and 0.5 which do not sum to one. 7Topics:: 8Examples:: 9Theory:: 10Faq:: 11See_Also:: 12
