Dear workshop community,
We will convene for the Applied Statistics Workshop (Gov 3009) this
Wednesday (10/17).
The speaker is* Susan Murphy *(Harvard Stats + SEAS) who will be presenting
her work "Stratified Micro-Randomized Trials with Applications to Mobile
Health".
*Where:* CGIS Knafel Building, Room K354 (see this link
<https://map.harvard.edu/?bld=04471&level=9> for directions).
*When: *Wednesday, October 17th at 12 noon - 1:30 pm.
*Abstract:* Technological advancements in the field of mobile devices and
wearable sensors make it possible to deliver treatments anytime and
anywhere to users like you and me. Increasingly the delivery of these
treatments is triggered by detections/predictions of vulnerability and
receptivity. These observations are likely to have been impacted by prior
treatments. Furthermore the treatments are often designed to have an impact
on users over a span of time during which subsequent treatments may be
provided. Here we discuss our work on the design of a mobile health smoking
cessation study in which the above two challenges arose. This work involves
the use of multiple online data analysis algorithms. Online algorithms are
used in the detection, for example, of physiological stress. Other
algorithms are used to forecast at each vulnerable time, the remaining
number of vulnerable times in the day. These algorithms are then inputs
into a randomization algorithm that ensures that each user is randomized to
each treatment an appropriate number of times per day. We develop the
stratified micro-randomized trial which involves not only the randomization
algorithm but a precise statement of the meaning of the treatment effects
and the primary scientific hypotheses along with primary analyses and
sample size calculations. Considerations of causal inference and potential
causal bias incurred by inappropriate data analyses play a large role
throughout.
*All are welcome! Lunch is provided! *
