Hi
Question about dbscan. I am -just- learning about it, so I'm not even sure I can use it.
I have indicators by county, for example, total mortality rates. Supppose I have a list of counties and their values, I'll just list some of them here:
23 640
12 642
44 775
56 897
57 4,484
Looks like county 57 is outside the cluster of other counties.
Is this the sort of thing for which I can use dbscan or cluster analysis? Is there a 'gentle' introduction to dbscan or cluster analysis? I got this
Anything more introductory?
Could try Primary Component Analysis .
proc pls
proc pca
@Rick_SAS wrote blogs about how to identity outliers .
Thanks, I will look at primary components analysis.
