Principal Components Analysis Options

Display

Specifies which output should be displayed by a Principal Components Analysis.

Latent Roots	latent roots (eigenvalues)
Loadings	Principal Component Loadings (latent vectors/eigenvectors)
Scores	Principal Component Scores
Significance Tests	Tests for equality of the smallest roots
Residuals	Residuals
Scree diagram	displays a scree diagram

Specifies how many latent roots and vectors are displayed (and saved); the residuals are formed from the remaining dimensions.

Specifies graphical display of the results from the analysis.

Scatter Plot of Principal Component Scores	draws a scatter plot matrix of the scores. The number of dimensions displayed in the plot will be equal to that specified above
Display Labels	provides a space for you to specify a text containing labels for the individual points displayed in the plots. The text should be equal in length to the data variates
Scree Plot	draws a scree plot of the ordered eigenvalues. The number of eignevalues will be equal to the number specified in the Number of Dimensions field
