Panda_nuts Nut-Cracking Frequency?

Yes, some individuals were observed much more than others. There's a practice problem at end of the chapter that focuses on this I think.

Is the question in 2E? Afaict, the Qs seem to be focused on the more traditional aspects of the model, rather than the number of measurements per chimpanzee per-se...

Well anyways, my concern was that it's not immediately clear to me whether you could use the same model for the data if the number of measurements per chimpanzee is skewed like this, so I just wanted to put this out there. I'm concerned that the validity/meaning of the parameters/model can change with the # of measurements.

Well, that's interesting--I'm curious then, am I just over-thinking things regarding considering the number of measurements? 😅 What's your take?

Whether imbalance matters or not depends upon the causal structure and the target of inference. So yeah, it can matter and is worth investigating in most cases. But often it will just be a matter of precision, not of bias.

It depending on the causal structure and target of inference makes sense to me.
