MANOVA

Data

This specifies the list of Y variates to be analysed. The

button allows multiple selections to be copied from Available Data.

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. This can be left blank with unstructured (completely randomized) designs.

Factorial

Controls the level of interactions to be fitted - an integer indicating the highest order interaction to include from the Treatment Structure. Specifying zero will fit just main effects; the maximum possible is 9.

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 model formula for a description of each.

Covariates

Select the check box if you want to perform analysis of covariance. In the corresponding input field you can list the covariates for the analysis. If there is more than one, their names may be separated by spaces or commas.
