16 Some Conclusions and Recommendations
The Gartner Business Intelligence & Analytics Summit, March 29, 2015, in Las Vegas, NV, featured a BI Bake Off: Visual Data Discovery with Qlik, SAS, Tableau and TIBCO. Michael O’Connell, Chief Data Scientist, TIBCO Software, has provided his results, but the data set is proprietary. The author has provided an open data set for a Bakeoff at the June 1st Federal Big Data Working Group Meetup. The data set is documented in a knowledge base and the results for UK, US HUD-VA HAI, and Fairfax Virginia County are shown in a TIBCO Spotfire file. Homeless data analytics and visualizations can inform decision makers and the public about the statistics and geographic “hot spots” of this serious social problem.
