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