Use the marginal fitted equations to estimate the population means of the response at different levels of the fixed factors and different values of covariates. The marginal fitted equations assume the means for the random factor terms are zero.

Use the conditional equations to calculate the conditional means for the response at the specific levels of fixed and random factors. Conditional implies conditional on the given levels of the random factors.

Because a mixed effects model include factors, the fitted equations are displayed in a table for all combinations of the factor levels in the model.
