Important: The stats package has been deprecated. Use the superseding package Statistics instead.

The stats[transform] subpackage provides various tools for transforming lists of statistical data.

Each command in the stats[transform] package can be accessed by using either the long form or the short form of the command name in the command calling sequence.

The following is a list of available commands.

To display the help page for a particular stats[transform] command, see Getting Help with a Command in a Package.

Some commands either require or use parameters in addition to the data given as arguments. These parameters appear as an index to the command name. See transform[standardscore] for an example.

If a particular call cannot be evaluated, for example trying to find the mode of a statistical list that contains a non-numeric entry, then the call is returned unevaluated. Information is provided in the variable `stats/lasterror` as to the reason why a call was not evaluated. Also, this information is automatically given if infolevel[stats] has a value greater than or equal to one, prior to the unsuccessful call.
