Yes but I fail to see why you consider Drake-style reasoning as an alternative to traditional hypothesis testing in the first place.
I want to know, in our example, whether the power outage in actual fact had a positive affect on the birthrate.
The Drake-like formula does not help me answer that question. It only generates a probable number of anomalous births based on the assumption that power outages increase birthrates. I still need conventional statistics to tell me with what degree of confidence I can hold that assumption.
