Bob,

If the 'binary' variables are represented as 0 or 1, the mean is the same as the percent endorsing (answer=1) the variables, so Norusis' recommendation works well.
Means do not work for nominal (categorical data).

Subject: [SPSSX-L] Syntax to obtain variable information about cluster membership

Dear all,

In 'IBM SPSS Statistics 19 Statistical Procedures Companion' Norusis
noted: "To see how clusters differ on the variables used to create them, save the cluster membership number using the Save command and then use the Means procedure, specifying the variables used to form the clusters as the dependent variables and the cluster number as the grouping variable"

I have two questions:

1) Is it possible to obtain information about the variables when the variables are binary?

2) if so, I was hoping someone could advise me regarding the syntax to obtain information about cluster composition, assuming variables var1 ....
var11). I assume the use of the means command would not apply for binary data.

Any assistance is appreciated,

Bob
