CELLS Subcommand (MATRIX DATA command)
CELLS specifies
the number of within-cells records in the data. The only valid specification
for CELLS is a single integer,
which indicates the number of sets of within-cells information that MATRIX DATA must read.
-
CELLSis required when there are factors in the data and ROWTYPE_ is implicit. - If
CELLSis used when ROWTYPE_ is specified onVARIABLES,MATRIX DATAissues a warning and ignores theCELLSsubcommand.
Example
MATRIX DATA VARIABLES=F1 VAR1 TO VAR3 /FACTORS=F1 /CELLS=2
/CONTENTS=(MEAN SD N) CORR.
BEGIN DATA
1 5 4 3
1 3 2 1
1 9 9 9
2 8 7 6
2 6 7 8
2 9 9 9
1
.6 1
.7 .8 1
END DATA.
- The specification for
CELLSis 2 because the factor variable F1 has two values (1 and 2) and there are therefore two sets of within-cells information. - If there were two factor variables, F1 and F2, and each had two values, 1 and 2,
CELLSwould equal 4 to account for all four possible factor combinations (assuming all that 4 combinations are present in the data).
