WebbExample 1: Scree plots after principal component analysis Multivariate commands, such as pca and factor (see[MV] pca and[MV] factor), produce eigenvalues and eigenvectors. The screeplot command graphs the eigenvalues, so you can decide how many components or factors to retain. We demonstrate scree plots after a principal component analysis. WebbThe scree plot method draws a straight line for each factor and its eigenvalues. Number eigenvalues greater than one considered as the number of factors. Here, you can see only for 6-factors eigenvalues are greater than one. It means we need to choose only 6 factors (or unobserved variables). Performing Factor Analysis
