I am using the Oceanic Tool Complexity model described in Statistical Rethinking to evaluate my ecological data. I am deconstructing the model per https://bookdown.org/connect/#/apps/1850/access (section 10.2, search “bit by bit”) to calculate the WAIC for each variation of the model.
However, the 5 WAIC values are not very different from each other. How do I recognize if a sub-model’s WAIC value is meaningfully different compared to its related sub-model WAICs? Thank you.
