Thanks Kieren! I was interpreting it to be the expectation of a geometric distribution (i.e. mean length assuming a constant annual probability of leaving), which I think is the correct way to interpret that number? Let me know if that’s wrong though!
The assumption that length is geometrically distributed might not be warranted, I’m not sure.
Thanks, Ben! That all seems fair enough for these purposes.
Fwiw, I think that number might be more the arithmetic mean of some observations. Interpreting it as a geometric mean seems like it doesn’t strongly violate much, but I think the geometric mean is going to be a little bit lower.
But yeah, I doubt it makes much of a difference in the scheme of things!

Thanks again for sharing all this :)
