Principal Components Analysis Options

Use this to select the output to be generated by a principal components analysis and options used in the analysis.


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.


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
