A variables specification is required directly after
the command name. The specification can be either a variable list
or the keyword ALL.
The CATEGORICAL, MAXCAT, and ID subcommands, if used, must be placed
after the variables list and before any other subcommand. These three
subcommands can be in any order.
Any combination of description and estimation subcommands
can be specified. For example, both the EM and REGRESSION subcommands
can be specified in one MVA command.
Univariate statistics are displayed unless the NOUNIVARIATE subcommand is specified. Thus,
if only a list of variables is specified, with no description or estimation
subcommands, univariate statistics are displayed.
If a subcommand is specified more than once, only
the last subcommand is honored.
The following words are reserved as keywords or internal
commands in the MVA procedure: VARIABLES, SORT, NOSORT, DESCRIBE, and WITH. They cannot be used as variable names in MVA.
The tables Summary of Estimated
Means and Summary of Estimated
Standard Deviations are produced if you specify more than
one way to estimate means and standard deviations. The methods include
univariate (default), listwise, pairwise, EM, and regression. For
example, these tables are produced when you specify both LISTWISE and EM.
