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.

개념

Mixed-Effects Models
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).
