- We monitor average response probability for active cases.
- I uses estimates from these models to determine the next step in experiments.
If I'm interested in the average impact of adding an 8th call to active cases, I might get a different estimate early in the field period than later.
In practice, the impact of this isn't as severe as you might think and there are remedies. Which leads me to the self-promotion part of this post ... I'll be presenting on this topic at AAPOR this year.
