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.
