Mixed-Effects Models Using nlmefit and nlmefitsa
Fit a mixed-effects model, plot predictions and residuals, and interpret the results.
Examining Residuals for Model Verification
Examine the stats
structure, which
is returned by both nlmefit
and nlmefitsa
,
to determine the quality of your model.
Mixed-effects models account for both fixed effects (which represent population parameters, assumed to be the same each time data is collected) and random effects (which act like additional error terms).
