Where the article explains it
Their unified framework, built on the earlier Cormack-Jolly-Seber approach, treats and p as estimable quantities rather than assumed constants, and — critically — provides goodness-of-fit tests to check whether the assumption that all animals of a given class share the same and p is actually defensible for the data in hand.
The passage around this formula
…counts and instead build an explicit statistical model of the capture history — the string of detections and non-detections for each individual across sessions — with separate parameters for survival probability ( ) between sessions and capture probability ( p ) within a session [ 2 ] . Their unified framework, built on the earlier Cormack-Jolly-Seber approach, treats and p as estimable quantities rather than assumed constants, and — critically — provides goodness-of-fit tests to check whether the…
