I have run a quasipoisson spatial model via GAM (NB just wouldn't work) and I am getting the following output of one of my parameters (COR.YEARLY.MEAN). Does this suggest an error in the model fit? The model seems to have converged. Apologies for the lack of reproducible example but it didn't really seem warranted in this case. Thank you for the assistance.
