Everyone Wants a Churn Model
Rarely do I ever get asked to make churn estimates for someone who needs to bring the full power of a proportional hazards model to bear. Besides, the person asking for churn estimates doesn’t actually want to know “what is the probability someone churns eventually?” (Spoiler: it’s 1.)
A Motivating Example
We were studying how microglia affect neuronal networks using a standard imaging experiment: 3 mice, 3 coverslips per condition, about 20 neurons measured per coverslip. Our question: Does LPS activation significantly increase PNA signal?
A while back, I wrote a short piece about planning scientific projects for New Science. The article explores systematic approaches to identifying impactful research questions and structuring PhD projects for maximum scientific contribution.
