Mixed effects model
Seasonal distance predictor
Survey tow year days
2017 and 2020 omitted.
Median year day
2017 and 2020 omitted.
Seasonal temperatures by season
Across all tows, are surveyed spring temperatures in the Mid-Atlantic bight comparable to the surveyed fall temperatures in the Gulf of Maine?
Linear mixed effects model
SOE 2024 feeding guilds
Linear mixed effects regression (lmer)
dist_km ~ delta_year_day + est_year*SOE_24 + (1|est_year) + (1|comname)
Generalized linear mixed model using template model builder (glmmTMB)
dist_km ~ delta_year_day + est_year*SOE_24 + (1|year_fac) + (1|comname), family=Gamma(link="log")
Species specific glmm using REML
dist_km ~ delta_year_day + est_year*comname + (1|year_fac), family = Gamma(link = "log"))
