It is often convenient
to define a constant of fixed value on the
random variable form. This is done by placing the word Constantor Fixed in
the cell used for the distribution type. Only the first three
letters are used for identification, so con or fix works
as well. This distribution has a single parameter which is
the value of the constant.
The examples below represent the constants 1, 2 and 3. The
examples were constructed on the general form. Only
the first parameter is relevant. There is no button on the Distribution
dialog for the constant distribution, but any
distribution can be changed to a constant by simply changing
the distribution identity.
