Real valued point histogram variable

Specification

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 real variable

Required abscissas

Real abscissas for a point histogram

Required counts

Counts for real-valued point histogram

Optional initial_point

Initial values

Optional descriptors

Labels for the variables

Description

This probability mass function is real-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 real relative to the other specified reals.

Examples

histogram_point_uncertain
  real = 2
  pairs_per_variable = 2               3 
  abscissas          = 3.1415 4.5389   100 200.112345 300
  counts             = 1      1        1   2          1

There are two variables, the first one has two possible real values which are equally probable. The second one has three possible real value options, and 200.112345 is twice as probable as either 100 or 300.
