I have my data from the official statistics office of my country and I rechecked multiple times already. I have a big outlier skewing all my glm (poisson) modells to the extreme (like 5 times the deviance). I tested deleting the row of data and i get the expected results with a good fit. Since I'm not allowed to do this without good reason (will call them tommorrow and check for possible error).

Is there a way to deal with this, if its indeed correct?

Looks kinda like this, sorry bad with formatting.

2 87 85 84 79 93 83 88 91 76

with 2 being the obvious outlier.

Appreciate it!
