SpletPrincipal Components Analysis (PCA) uses algorithms to "reduce" data into correlated "factors" that provide a conceptual and mathematical understanding of the construct of … SpletEconomy. 0.142. 0.150. 0.239. Interpretation of the principal components is based on finding which variables are most strongly correlated with each component, i.e., which of these numbers are large in magnitude, the farthest from zero in either direction. Which numbers we consider to be large or small is of course is a subjective decision. SpletObjectives. Carry out a principal components analysis using SAS and Minitab. Interpret principal component scores and describe a subject with a high or low score; Determine when a principal component analysis should be based on the variance-covariance matrix or the correlation matrix; Use principal component scores in further analyses. get the gat lady
