that the following are true about the
The expressions are valid MATLAB® code.
Each expression is linear with a transformation.
There is exactly one expression for each parameter.
In each expression, a covariate is used in at most one term.
In each expression, there is at most one random effect (
Fixed effect (
theta) and random effect (
eta) names are unique within and across expressions. That is, each covariate has its own fixed effect.
If the previous requirements are true, then
