Bootstrap GOF-test with MARK Bootstrap procedure (1) Retrieve the model to be tested (full model) (2) The bootstrap procedure runs simulations of a “similar” encounter history file (same number of animals released at each occasion) based on estimates of the full model and then runs the full model on the simulated data (3) The procedure stores the deviance … of the simulated model and can repeat n times (n ≈ 500-1000) (4) GOF-test based on deviances of the simulated model versus deviance of the full model based on true data
