Dear list members, I have an ecological data set, and I want to account for the spatio-temporal structure of my data:
metric = response variable (continuous) zone = 3 zones (A, B and C) location = 12 sampling locations per zone min = minute hour = hour day = day metric zone location minute hour day 2.4 A 1A 1 1 1 2.7. A. 1A 2 1 1 1.7. C 1C. 45 3 5 If I want to compare the metric among the 3 zones, is it the following an appropriate model parameterization in lme4?: mod_01 <- lmer(metric ~ zone + (1 | location) + (1 | day/hour/min), data = my_data) Thank you very much in advance.
