This menu can be used to calculate marginal and conditional tests for all terms in a generalized 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 or 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 '*'.
Distribution
List of available error distributions. If you select the binomial distribution then you must supply the binomial totals in
the space provided. Alternatively, if you select the negative binomial you must supply the aggregation in the
space provided.
Link Function
Lists the available link functions. If you select the power link function then you must supply the exponent in the space
provided. Similarly, if you select the Logratio link function then you must supply the logratio in the space provided.
