This provides, for example, a useful method of checking equality of certain functions of i.i.d. random variables.

Reports are a very useful method for keeping track of important information.

More recently, scattering information from cosmic ray muons has been shown to be a useful method of radiography for homeland security applications.

These semantics render the partial sweeping operation a useful method for manipulating multivariate normal distributions.
