#JSM2018 Panel on CNSTAT report on Federal Statistics, Multiple Data Sources, and Privacy Protection, with @fraukolos kicking off The discussion 
#JSM2018 @fraukolos Goal of panel to evaluate combining data sources to possibly replace / augment surveys. Two reports out of the panel.
#JSM2018 @fraukolos Conclusions: Current Federal Statistical Agencies face threats from falling response rates, rising costs, increased desire for granularity and timelines
#JSM2018 @fraukolos Great graph on types of data. Aspirational Data are social media (what we aspire to show ourselves as) and transactional Data are interactions with computerized systems for transactions (purchases, for example)
#JSM2018 @fraukolos Gives example of difference of testing signal strength for mobile devices. Can send a car around to precisely measure signal strength on small strip; use crowd sourcing from mobile devices to get broad measurement
#JSM2018 @fraukolos Administrative, aspirational, transactional data all going to require work. May be out there, but needs to be processed, so not fast
#JSM2018 @fraukolos A new entity should be built to house data access (similar to Evidence-Based Policy Making commission)
#JSM2018 @fraukolos Second report goes into detail about statistical methods for combining multiple data sources. Can be hard when multiple data sources come in at different levels of analysis.
#JSM2018 @fraukolos Federal Statistical Agencies should clearly document processes that were used for combining, etc. Data - sharing code more generally could be good even without multiple data sources
#JSM2018 @fraukolos As we combine multiple data sources, what makes PII is more complicated (images contain identifying information even without names). (PII = personal identifying information)
#JSM2018 @fraukolos Techniques that give limits to the number of queries that can be asked of a database one thing to think about WRT differential privacy
#JSM2018 @fraukolos We survey folks should be comfortable claiming our TSE framework as useful for evaluating a dataset with multiple data sources. But need to think of more general quality framework as well
#JSM2018 @fraukolos A new entity should facilitate access to multiple data sources. It should be transparent in what the data sources are and what methods are for doing Linkage. Have a board of directors to guide its actions.
