976 MATRIX DATA<br />

• Because ROWTYPE_ is specified on VARIABLES, CONTENTS is optional. However,<br />

CONTENTS is specified for informational purposes. This is most useful when data are<br />

in an external file and the ROWTYPE_ values cannot be seen in the data.<br />

• Missing values for factors are entered as periods, even though CONTENTS is specified.<br />

N Subcommand<br />

N specifies the population N when the data do not include it. The only valid specification is<br />

an integer, which indicates the population N.<br />

• MATRIX DATA generates one record with a ROWTYPE_ of N for each split file, and it uses<br />

the specified N value for each continuous variable.<br />

Example<br />

MATRIX DATA VARIABLES=V1 TO V3 /CONTENTS=MEAN SD CORR<br />

/N=99.<br />

BEGIN DATA<br />

5 4 3<br />

3 4 5<br />

1<br />

.6 1<br />

.7 .8 1<br />

END DATA.<br />

• MATRIX DATA uses 99 as the N value for all continuous variables.
