= SPSS MRSets =

The '''`MRSETS`''' command creates '''multiple-response sets'''.

== Usage ==

{{{
mrsets /mdgroup name=foobarbaz variables=foo bar baz value=1.
mrsets /mdgroup name=foobarbaz variables=foo bar baz value=1 label="Foo, bar, and baz".
}}}

The '''`/MDGROUP`''' subcommand defines the series of variables that represent a '''multiple-dichotomy group'''. For numeric variables, the '''`VALUE`''' option must specify an integer. For string variables, it must specify a string value no longer than the shortest component variable.

An optional label for the set can be specified on the '''`LABEL`''' option. Alternatively, specify '''`LABELSOURCE=VARLABEL`''' and the set will inherit the label from the first component variable.

By default, SPSS will use the component variable labels (or if not labeled, variable names) as the set's value labels. Add the '''`CATEGORYLABELS=VARLABELS`''' option to explicitly allow this behavior, or add the '''`CATEGORYLABELS=COUNTEDVALUES`''' option to instead use the component value label of the counted value. (This could be useful if, for example, the value labels of `foo` are `0="Not foo" 1="Foo"`.) SPSS will warn if component variables have matching labels.

To define a '''multi-category group''', use the '''`/MCGROUP`''' subcommand. (This is useful if, for example, `foo` represents the first selection, `bar` represents the second selection, and so on.) The '''`LABELSOURCE`''' and '''`CATEGORYLABELS`''' options are not allowed on this subcommand. SPSS will inherit the first component variable's value labels, but also it will warn if any component variable has differing labels.



=== Delete ===

To instead delete a multiple-response set, specify the '''`/DELETE`''' subcommand.

{{{
mrsets /delete name=foobarbaz.
}}}



=== Display ===

To display information about a multiple-response set, specify the '''`/DISPLAY`''' subcommand.

{{{
mrsets /display name=foobarbaz.
}}}

== Data Model ==

The `MRSETS` command executes immediately. Pending transformations are ''not'' executed and the active dataset is ''not'' read.
