Integer valued point histogram variable


Alias: none

Argument(s): INTEGER

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

Optional initial_point

Initial values

Optional descriptors

Labels for the variables


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.


  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.
