Subject: Cluster Analysis Seems to Have Too Many Variables
Content-Type: text/plain; charset="us-ascii"
I have 1,619 variables. I am starting by doing a hierarchical cluster
analysis. From there I will use the centroids as seeds for the quick
cluster. The following code works with no problem if I bring the number
of cases down to 500. Is there a way for me to tell SPSS (v13) to set
aside more memory? I have found SET WORKSPACE but I'm at a bit of a
loss in figuring how much of a change I should make without compromising
other stuff I do in SPSS.
zcv1 TO zcv4
/MATRIX OUT ("C:\temp2\spssclus.tmp")
/VIEW = CASE
/MEASURE = SEUCLID
/STANDARDIZE = NONE.
SORT CASES BY id.
/MATRIX IN ("C:\temp2\spssclus.tmp")
/PRINT SCHEDULE CLUSTER(3, 7)
/SAVE CLUSTER(3, 7).
