How to generate the equation of a GLMM?
Dear all,
I have to obtain the equation of a GLMM. I hoped to do it using the
equatiomatic package, but it does not generate the equations for GLMM.
Any other package to generate it?
I have two different GLMMs:
- For the first one (glmer.nb(Zooplankton ~ offset(filtered volume) +
Temp + Sal + (1|stationNumber), data)) I think I managed to generate
the equation manually (the coefficients are below), but what I should
add as offset?
The equation: Y = 20.57 + 1.17 Temp -2.12 Sal +ai
ai ~ N(0, 1.32^2)
The coefficients:
Random effects:
Groups Name Variance Std.Dev.
stationNumber (Intercept) 1.702 1.324
Number of obs: 72, groups: stationNumber, 72
Fixed effects:
Estimate Std. Error z value Pr(>|z|)
(Intercept) 20.5694 12.6924 2.182 0.00146 **
Temp 1.1716 0.2222 3.823 2.41e-05 ***
Sal -2.1222 0.3710 -6.450 4.04e-05 ***

- For the other GLMM (glmer.nb(Zooplankton ~ offset(filtered volume) +
Light * Depth + (1|stationNumber), data)), how can I generate the
equation? What to put as offset?
The coefficients are:
Random effects:
Groups Name Variance Std.Dev.
Station (Intercept) 1.865 1.365
Number of obs: 102, groups: Station, 51
Fixed effects:

Many thanks in advance for your time and help,
All the best!
