delta strategy

Open slefores opened this issue 4 years ago • 2 comments

Hi,

I am interested in using VAST for a case study on which I am focusing only on positive CPUE values and I would like to know if the DELTA strategy is optional or not with VAST?

Thank you!

It sounds be feasible using ObsModel[2] = 3 instead of ObsModel[2] = 0, or ObsModel[2] = 4 instead of ObsModel[2] = 1, and also turning off FieldConfig[1:2] = 0. These changes to the defaults, respectively, turn off intercepts, and the spatial and spatio-temporal variation in the encounter-probability submodel.

I will try. Thank you for your answer!
