TRANSCRIPT
Data collection at CESR
CESR’s Nubis software provides tools for the collection of data using traditional interviewing techniques: Face-to-face, phone and self interviews.
Collected data in some 30 countries on five continents, usually in complicated longitudinal surveys (DLHS in India: 1.5 million respondents)
We can also collect data in the background. E.g: Physical Activity, GPS, heart-rate, and send that to a central server.Send short (follow-up) questions to cellphone or watch asking for details about observed activity or location.
UAS: Real-time, Contextualized data collection and intervention technologies
Just-In-Time Adaptive Data Collection and Intervention by smartwatch and smartphone
Mobile Technologies:Understanding Behavior in Real Time
• Sensors sensing behavior• GPS sensing place• Sound/device recog. sensing
conversation, other people, mood• EMA/SMS collects & provides data • On demand according to times, places, in
response to sensed events• Integrates wireless data from
wearable/deployable sensors • Record of phone, email, Internet use• Patterns of change over time and place• Real- or near-time data
transfer/feedback• Electronic records of financial
transactions

What is an Internet Panel?
• Any device that can connect to the Internet• Passive measurement, using bluetooth for
instance• Mobile devices of any sort• Essentially two types:
– Convenience (non-probability) panels– Probability panels
10
Probability Panels
• Selection probabilities known. – Need sampling frame (denominator)
• Get internet access for those without it.
11
Why are probability internet panels with low response rates superior to convenience panels?
• Coverage of non-internet population• Selectivity of respondents who sign up for
convenience panels.– 30% of online surveys completed by 0.25% of the
U.S. population (Miller, 2006) – 15-25% of vendor samples from a common pool of
respondents (Craig et al., 2013)– Panel participants belong to 7 online panels
(Tourangeau, Conrad, and Couper, 2013)

Financial Transaction Data• Financial aggregation firms like Mint.com and
Check.me have people share their financial passwords with them so that participants can be provided with summaries of their expenditures and savings.
• We ask UAS respondents to sign up with one of these financial aggregators and allow us access to the data. Potentially that will allow us to produce estimates of national consumption in real time.
