I am working on creating GLMMs to determine the effect of in-air noise on harbor seals (specifically the number present). I have a couple other fixed predictor variables (current velocity and time) and some random effects. As I am fresh out of undergrad, I have taken only one basic stats/R class and am thus very new to modeling. I am struggling to format my random effect variables in my models. I have used ChatGPT and Google to try and figure out how best to format them but am still not confident I am doing it correctly.
