Hi @Sarahbouclette,
Could you also share a histogram of your response? It may also be difficult for the optimizer if your response is strongly overdispersed. In this case, you may want to switch to a negative binomial distribution.
Yes, here is to examples of response histograms. But I have the same error message with Nbinom.
Hi @Sarahbouclette,
Sorry, it is hard to say if it is because of the data or because of convergence problems in the model. If this is ok for you, could you please send me your code+data (via email) so I can take a look myself?
Hello, I tried my best to understand and find a solution but I'm stuck. My problem is that i want to use a poisson distribution on eDNA data. So, each species for each sample is described as its number of reads/Total number of reads of the sample. When i try to run my model:
I saw that someone already has this issue and you recommended to change the learning rate and to scale the data. I tried both and it's still not working. Do you have an idea of what can I possibly change?
Thank you
