Is there such thing as p2?

[Jasperf]

Hi there,
I've conducted a two season occupancy modelling approach and obtained managed to calculate psi2 using equation 7.4 on page 199 of the main textbook.
psi2=psi(1-epsilon) + (1-psi)(gamma)

however, i could not find any equation that could aid me in manually calculating p2 value in the book. Is there a way to find p2 (detection probability for season 2)??

By the way, I read about the earthquake in south island. Is everything fine over there with you guys??

No calculation is needed, p2 is reported directly as part of the output. Note that your estimate of psi2 is also given in the output, right near the bottom under derived parameters (presuming you've used the multi-season model).


I'm fine, about 360km south of the epicentre, but plenty of people in Christchurch are hurting really bad. 103 confirmed dead, about 200 still missing, 169 in hospital with serious injuries, 25% (of city with about 400k people from memory) without power, 80% without water and sewerage, a huge number of buildings in the CBD and surrounding suburbs will have to be condemned, even those that are currently still standing. Repair bill is going to be at least 10 billion dollars (no matter which currency you use) according to reports. With the 2-degrees of separation rule here in NZ, I'm sure there are some kiwi's on the list that knows someone, who knows someone that is caught in the middle of it all. Add to that, they're still experiencing frequent (like 1 an hour) aftershocks. Not good.

Thanks darryl for the help.

It was tragic. I'm sorry to hear that. My condolences to the victims and prayers to their families.
