Gun Violence Incident Grouping via PCA
Note (Oct. 14, 2016): Part of this work was used in a collaboration between the AP here and USA TODAY NETWORK here.
The Gun Violence Archive (GVA) has for each event a list of characteristics. There are 92 distinct tags that are used. Many of these tags are either redundant or unnecessarily specific for the kinds of questions I am interested in investigating:
- What are the most frequent kinds of gun-related incidents?
- Where are they located and which demographic groups are affected by them?
