If the model includes random or repeated effects, the Parameter column in the Parameter Key worksheet contains the variance parameter names assigned by the Linear Mixed Effects object. If the Group option is not used in the model or if there is only one random or repeated model, then indices are not used in the parameter names.
Otherwise, two indices are appended to the variance parameter names in order to clarify which random or repeated model, or group, the variance parameter addresses. The first index indicates the random model or repeated model to which the parameter applies. An index of 1 indicates the model on the Random 1 tab in the Variance Structure tab. The highest index indicates the repeated model if there was one. The second index is the group index indicating that the parameters within the same group index are for the same group level.
Source: Random if the parameter is from a random model. Repeated if the parameter is from a repeated specification. Assumed if the variance parameter is the residual.
Type: User-specified variance type, or Identity, if the residual variance.
Bands: Number of bands or factors if appropriate for the variance type.
Subject_Term: Subject term for this variance structure, if there was a subject.
Group_Term: Group term for this variance structure, if there was a group.
Group_Level: Level of the group that this parameter goes with, if there was a group.
