Assesses order of ante-dependence for repeated measures data and calculates
overall tests based on a specified order. A repeated-measures design is one in
which subjects (animals, people, plots, etc.) are observed several times. Each
subject receives a randomly allocated treatment, either at the outset, or
repeatedly through the experiment. The subjects are observed at successive
occasions to see how the treatment effects develop.
Data at Successive Times
Used to enter the names of the variates, one for each time point, containing
the data observations which are to be analysed. The

allows multiple selections to be copied from Available Data
Order of Ante-dependence
Select Assess to assess the order of ante-dependence. You can specify the
maximum order against which to test in the specified field entitled
Maximum. To calculate overall tests based on a specific order select
Set. You can specify the number of past times for which to adjust in the
specified field entitled Order.
Treatment structure
The treatment terms to be fitted are specified by entering a model formula.
Block Structure
The underlying structure of the design is defined by entering a model formula.
Available Data
This lists data structures appropriate to the current input field. It lists
either factors for use in specifying the treatment and block 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 and block
model formulas. Double-click on the required symbol to copy it to the current
input field. You can also type in operators directly. See Operators in model
formulae for a description of each.
Level of Interaction
Controls the maximum order of interaction to be generated when you use
model-formula operators like *. The default is to include all interactions, up
to those involving nine factors. (You cannot ask for more than nine.)
