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.

Manuel
