Method for Estimating Phi

This controls whether the parameter phi is estimated for regression models by REML or by maximum likelihood.

Estimate Constant Term

Specifies whether to include a constant in the regression model. In simple linear regression this omits the intercept, in other words the fitted line is constrained to pass through the origin.

Weights

A variate that can be used to allow data units to have unequal weights. The name of the variate can be entered into the space provided or double-clicked across from the list of available data.

Level of Interaction

You can control the maximum order of interaction to be generated when you use model-formula operators like '*'. The default is to include all interactions.

Maximum iterations to estimate phi

Specifies the maximum number of iterations (default 100) used to estimate phi.
