This menu provides facilities for analysis of multivariate linear mixed models and estimation of variance components using
the method of residual maximum likelihood (REML), which is also sometimes called restricted maximum likelihood.
Data
This specifies the list of data variates to be analysed. The
button allows multiple selections to be copied from Available Data.
Fixed Model
The fixed model describes imposed treatment factors and covariates for which the effect of specified levels or values are of
interest. The model is described using a formula, which can combine main effects and interactions of factors and also covariates.
Random Model
The random model is generally used to describe those factors for which the values present in an experiment can be considered drawn
from some large homogeneous population. The model is described using a formula, which can combine main effects and interactions of
factors and also covariates.
Covariance Model Across Data
Allows you to specify the type of covariance model across the data. You can select either Identity or
unstructured.
Available Data
This lists data structures appropriate to the current input field. The contents will change as you move from one field to the next.
Double-click on a name to copy it to the current input field; alternatively, you can type in the name directly.
Operators
This provides a quick way of entering operators in the fixed and random model formulas. Double-click on the required symbol to copy
it to the current input field. You can also type in operators directly. See model formula for
a description of each.
