This menu can be used to calculate marginal and conditional tests for all terms in a linear model. It also performs
pooled testing of all main effects, of all 2-factor interactions, etc.
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 the
name directly into the input field.
Response Variate
Provides a space for you to specify a response variate containing the data.
Model formula of List of explanatory data
Specifies the model candidate terms in the fitted model, which may be set using a model formula or using a list of terms
separated by commas.
Terms always included in the model
It is sometimes desirable to include specific terms in every model. Such terms may be specified by in this box, which may
be set using a model formula or using a list of terms separated by commas.
Operators
This provides a quick way of entering operators in the Model Terms formula. 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.
Factorial
You can control the maximum order of interaction to be generated when you use model-formula operators like '*'.
