Hi there, I wonder how to create SCREE plot by using principal component score only. Because metadata is not available for PCA, I only have PC score at hand. See following example. example data: options validvarname=any;
data Jobratings;
input 'Communication Skills'n 'Problem Solving'n
'Learning Ability'n 'Judgment Under Pressure'n
'Observational Skills'n 'Willingness to Confront Problems'n
'Interest in People'n 'Interpersonal Sensitivity'n
'Desire for Self-Improvement'n 'Appearance'n
'Dependability'n 'Physical Ability'n
'Integrity'n 'Overall Rating'n;
datalines;
