  • Cluster analysis - insufficient observations

    Hello,

    I am trying to do a cluster analysis with about 410 baseline survey variables and 2000 observations. I plan to look at symptom subgroups using dendrograms.
    I keep getting the error insufficient observations r(2001). I do have quite a bit of missing data.
    Does anyone have any suggestions on what the issue might be?
    This is the code: cluster singlelinkage v1-v410, measure(L2) name(clustertest)

    Thanks,
    Jennifer

    Problems with missing values are the most likely reason for this.
