...rVariables
The ``r'' stands for ``regular.'' rVariables are the type of variables that CDF has always supported. Perhaps ``traditional'' would have been a better term. We also considered ``related'' and ``correlated'' but those just didn't seem right.

...zVariables.
The ``z'' doesn't stand for anything special. We just like the letter ``z.''

...zVariables.
This is generally not recommended. In those situations where zVariables are necessary it is best to use all zVariables rather than a mixture of rVariables and zVariables.
