Specification

• Alias: None

• Arguments: INTEGER

Child Keywords:

Required/Optional	Description of Group	Dakota Keyword	Dakota Keyword Description
Optional		pairs_per_variable	Number of pairs defining each histogram point integer variable
Required		abscissas	Integer abscissas for a point histogram
Required		counts	Counts for integer-valued point histogram

Description

This probability mass function is integer-valued; the abscissa values must all be integers. The n abscissa values are paired with n counts which indicate the relative frequency (mass) of each integer relative to the other specified integers.

Examples

histogram_point_uncertain
  integer = 2
  pairs_per_variable = 2     3
  abscissas          = 3 4   100 200 300
  counts             = 1 1   1   2   1

There are two variables, the first one has two possible integer values which are equally probable. The second one has three options, and 200 is twice as probable as either 100 or 300.
