The Estimates tab provides a mechanism for creating custom hypothesis tests. Estimates can only be computed using the fixed effect model terms set in the Model Specification field. Since the Estimates tab produces estimates instead of contrasts, the coefficients do not have to sum to zero and more than one model term can be added to the Effect field. The marginal interval is generated for each estimate.
For more on estimates in the linear mixed effects model, see the “Estimates” section.
The Fixed Effects Model Terms box lists all the fixed effect model terms specified in the Fixed Effects tab. Drag a term from the Fixed Effect Model Terms box to the Effect field to compute the estimates for that term. The conditions for using model terms as effect variables are:
Interaction terms and nested terms can be used if they are used in the model.
If the fixed effects model includes an intercept, which is the default setting, then the intercept can be used to produce an estimate.
If the intercept term is used as an effect for an estimate it works like a regressor, which means only one coefficient value is used for the intercept.
