Use this to select the output to be generated by a principal components analysis and options used in the analysis.
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 |
| Residuals | Residuals |
| Significance tests | Tests for equality of the smallest roots |
| Scree diagram | Displays a scree diagram |
Number of dimensions
Specifies how many latent roots and vectors are displayed (and saved); the residuals are formed from the remaining dimensions.
Graphics
Specifies graphical display of the results from the analysis.
| Scatter plot matrix 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 | 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 eigenvalues will be equal to the number specified in the Number of dimensions field |
