There were 50 or more warnings (use warnings() to see the first 50)
The thing is that the caracter "Wuerfel" is random generated
and it shouldn' t be significant.
It would be realy great if you could help me.
The most obvious guess is that sb_ek_ber probably is not Poisson distributed.
I tried it in another statistical programm and I got the values that I expected but for my bachelortheses I need to do it in R.
And what do you expect us to do with that bit of information? Did you check the distribution of the response variable? For all we know, it might have values of 99999 indicating missing values to "another statistical program".
