Term<br />

Contrast<br />

Name of the factor.<br />

Estimate for the factor. For orthogonal designs, this number is the same as<br />

the regression parameter estimate. This is not the case for non-orthogonal<br />

designs. An asterisk might appear next to the contrast, indicating a lack of<br />

orthogonality.
