I was recently asked for some code to show how I created the charts in my paper, Tables and Graphs for Monitoring Crime Patterns (Pre-print can be seen here ). I cannot share the data used in the paper, but I can replicate them with some other public data. I will use calls for service...
Last week the SPSS team was in the Esri User Conference. We had a booth shared with other IBM teams and also a great session on Tuesday afternoon. We announced new SPSS (Modeler and Statistics) extensions that integrate with Esri services. These are the first set of extensions and we have more...

Motivated by visualizing overlapping intervals from the This is not Rocket Science blog (by Valentine Svensson) I developed some code in SPSS to accomplish a similar feat. Here is an example plot from the blog: It is related to a graph I attempted to make for visualizing overlap in ...
For a project I have been estimating group based trajectory models for counts of crime at micro places. Synonymous with the trajectory models David Weisburd and colleagues estimated for street segments in Seattle. Here I will show how using SPSS and the R package crimCV one can estimate...

The other day I showed how one could make an edge list in SPSS , which is needed to generate network graphs. Today, I will show how one can use an edge list in long format to identify neighbors for higher degree relationships. So to start, what do I mean by a neighbor of higher degree...
