String (categorical) 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 string variable  
Required  abscissas  String abscissas for a point histogram  
Required  counts  Counts for stringvalued point histogram  
Optional  initial_point  Initial values  
Optional  descriptors  Labels for the variables 
This probability mass function is stringvalued; the abscissa values must all be strings. The n
abscissa values are paired with n
counts
which indicate the relative frequency (mass) of each string relative to the other specified strings.
histogram_point_uncertain string = 2 pairs_per_variable = 2 3 abscissas = 'no' 'yes' 'function1' 'function2' 'function3' counts = 1 1 1 2 1 descriptors = 'vote' 'which_function'
Here there are two variables, the first one ('vote') has two possible string values 'yes' and 'no' which are equally probable. The second one has three options for 'which_function', and 'function2' is twice as probable as 'function1' or 'function3'.
