I ran a SAS macro and output a tetrachoric correlation matrix of 236
variables successfully. However, when I ran a factor analsyis using the
matrix as the infile, it fails. Although I have specified 'corr' for
_type_, SAS said that:
"Data set WORK.MATRIX2 has _TYPE_ and _NAME_ variables but is not
TYPE=ACE, CORR, COV, EST, FACTOR, SSCP, UCORR, or UCOV.
ERROR: CORR matrix incomplete in data set WORK.MATRIX.
The following is the SAS program. I would appreciate it if any SAS expert
out there can give me a hand:
data matrix (type=corr); infile "plcorr2.txt";
_type_='corr';
input _name_ $ as1-as24 bs1-bs24 cs1-cs25 ds1-ds25 es1-es25 fs1-fs25
gs1-gs25 hs1-hs60;*/
data matrix2; set matrix;
proc factor data=matrix method = prinit scree;
run;
