Essentially a form of targeted dimension reduction, an envelopes is a nascent construct for increasing efficiency in multivariate statistics without altering the traditional goals, sometimes producing gains equivalent to taking thousands of additional observations. This is made possible by recognizing that the data may contain unanticipated variation that is effectively immaterial to estimation or prediction.

All of these methods are available with the standard statistical language R which I will use to
present the examples.
