Identity Design Matrix<\/b><\/span><\/p>\n

To fill in the <\/span>design matrix<\/a><\/span> with an Identity matrix, select the FillCol, Identity choices.\u00a0 The matrix is filled with zeros, and ones on the main diagonal.\u00a0 This command is useful in filling the matrix after you have filled cells with incorrect values.\u00a0 As an example, suppose the following design matrix is on the screen, consisting of all zeros.<\/span><\/p>\n
