We’re just getting started analyzing the social distancing metrics and have a few questions!
(1) We are wondering if we should be scaling the metrics using the candidate_device_count
over the device_count
, and if that should apply to all social distancing metrics. This question follows directly from a conversation started January 19th 2021 between @Ryan_Kruse_MN_State, @Aaron_Flaaen_Federal_Reserve_Board, and @Francisco_Utrera, which I followed the thread for, but wanted to know if there were any takeaways regarding which variable works best for scaling.
(2) We are interested in getting indices of change for social distancing metrics from a pre-pandemic baseline and are wondering what others’ experiences have been as to the ‘best’ way to define this baseline?
I’ve seen this done as a difference or ratio from a single week in early 2020, e.g. the week of March 1, 2020, before any interventions were in place.
I’ve also seen this done as a difference or ratio from a similar day in the previous year, e.g. if we’re getting the change from a baseline for a metric on 10-24-2020, a weekday, we’d use as the baseline the average weekday metric for weekdays in October 2019.
(3) Due to the data product change to v2.0 during Jan1-May 9, 2020, should we assume that we cannot get indices of change for data during this time period, if defining the baseline as coming from a similar day in 2019? That is, is it not possible to create indices of change that compare data coming from v2.0 and from v2.1 time periods?
I realize this is a lot of questions — answers to any of the above would be helpful! Thanks in advance.
