Integer valued point histogram variable

## Specification

Alias: none

Argument(s): 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
| Optional | initial_point | Initial values for variables
| Optional | descriptors | Labels for the variables

## 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.
