Option Name
Description
Methods
Number of components
specifies the number of principal components to compute.
Details
Analyze
specifies whether to compute the principal components from a correlation or covariance matrix.
Correct the covariances or correlations for the means
specifies whether to include the intercept in the model.
Standardize variance of scores
specifies how to standardize the principal component scores. The variance of the scores can be equal to 1 or equal to the corresponding eigenvalue.
Specify a prefix to label the components
specifies a prefix for naming the principal components. By default, the names are Prin1, Prin2, …, Prinn. If you specify Abc as the prefix, the components are named Abc1, Abc2, Abc3, and so on.
Plots
By default, an eigenvalue by component plot (scree plot) is displayed in the results. You can also include any of these plots:
  • scores for pairs of components. You can specify whether to include a prediction ellipse.
  • component scores matrix.
  • component profile patterns.
  • patterns for pairs of components.
