Best model

Hello,

I built several ddf models,

What I am supposed to do if the best model (with lowest AIC) hasn't a good fit ( p value <0.05 when using the ddf.gof function ) ?

Can I keep this predicted distance value or it is better to built another model?

Do you have any suggestions for me ?

Regards

Angela

Setting aside AIC rank for the moment, making inference based upon a model that does not fit your observed data does not result in defensible estimates. Your estimates will be open to criticism that you've used a model that is in conflict with the data you observed.

More reliable estimates are derived from employing models that fit your distance sampling data.

Hi!!!

I solved the goodness of fit problems with the the truncation of the most distant detections
