The General Treatment Structure (no Blocking) menu allows you to fit
completely general treatment models to data from designs where there
is no blocking of any sort.
Design
Can be used to switch to other, more specific types of designs.
Y-Variate
This should be set to the variate containing the data values.
Treatment structure
The treatment terms to be fitted are specified by entering a model formula.
Contrasts
Generates a menu that allows you to specify one or more treatment contrasts that you wish to analyse.
Interactions
Controls the level of interactions to be fitted - you can indicate either All Interactions, or
just main effects (No Interactions), or indicate the level of interaction (that is, set a limit
on the maximum number of factors in the treatment terms that are fitted).
Available Data
This lists data structures appropriate to the current input field. It lists either factors for use in
specifying the treatment structure, or variates for specifying the data and additional covariates. 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.
Operators
This provides a quick way of entering operators in the treatment model formula. Double-click on the required
symbol to copy it to the current input field. You can also type in enter operators directly. See
model formula for a description of each.
Covariates
Select the check box if you want to perform analysis of covariance. This
produces an additional field in which you can list the covariates for the
analysis. If there is more than one, their names must be separated by spaces or
commas.
