Subunit Discrete Distributions
 - Constant

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.
