R dredge function
WebIt is notable that because you did not define a scope or direction parameter step defaulted to a 'backwards' step approach, in which variable terms are evaluated for dropping at each step, at each step if dropping the selected variable decreases the AIC it is removed from the model and the entire process repeats until it becomes the case that no … WebThe auk function filter_repeat_visits () is designed to extract a subset of eBird data suitable for occupancy modeling. Using the function, we first filter the data to only sites that have at least 2 visits ( min_obs ). We also define the maximum number of repeat visits ( max_obs) as 10 visits or checklists.
