Hi,
I try to calculate à typology of sociocultural milieux with data from
the ESS survey. After having calculated three continuous variables: ses
culture populism as input for the typology I now want to cluster them.
N = 2420.
QUICK CLUSTER ses culture populism
/CRITERIA CLUSTERS(8)
/SAVE CLUSTER(milieu).
The result is incomprehensible to me.
The majority of cases disappeared, though there are few missings in the
original variables.
And the clusters have a NaN entry which says nothing to me. The PSPP
Help tries to explain what NaN means, but I don't understand it.
And I don't see how to run a cluster analysis that works.
