In my analyses of rural bird species, I came across the issue that, even though the function check_observations() tells me that I have enough data points to the model, the model run itself gives me an error. There are two separate errors, prumably related to using small datasets and/or short periods:
Error: Model non-estimable due to excessive high beta values.
Error: Data does not contain enough information to estimate model.
In the attached files, I illustrated the issue with similar data of three species: one that gives no errors, one that gives the first error, and one that gives the second error. Is it possible to make the function check_observations() tally with the data/observations/information that the model actually uses?
I faced the same problem. It seems to work for model 3, but for model 2 it fails even when there is a covariable level with no valid observations. Here a simple example:
The rtrim manual states that "For model 2 with covariates there must be at least one observation for every value of each
covariate, at each time segment defined by the change points." However, in this case there is no count value for habitat = 3 and even so, the output says sufficient.
Is this a bug? Or are we missing something?
