CONTRAST, BASIS, and ORTHONORM Keywords (MANOVA: Multivariate command)

You can control how the transformation matrix is to be generated from the specified contrasts. If none of these three keywords is specified on TRANSFORM, the default is CONTRAST.

CONTRAST. Generate the transformation matrix directly from the contrast matrix specified (see CONTRAST Subcommand (MANOVA: Univariate command)). This is the default.

BASIS. Generate the transformation matrix from the one-way basis matrix corresponding to the specified contrast matrix. BASIS makes a difference only if the transformation contrasts are not orthogonal.

ORTHONORM. Orthonormalize the transformation matrix by rows before use. MANOVA eliminates redundant rows. By default, orthonormalization is not done.

• CONTRAST and BASIS are alternatives and are mutually exclusive.
• ORTHONORM is independent of the CONTRAST/BASIS choice; you can enter it before or after either of those keywords.
