WebbA scree plot is a graph of eigenvalues against the corresponding PC number.9 The number of PCs retained is then subjectively determined by locating the point at which the graph shows a distinct change in the slope. 8 An example of a scree plot ( Figure 6) shows that most of the variance is contained in the first 20 eigenvalues.

WebbThis should be the case consistently after the first instance on the scree plot where the simulated eigenvalue exceeds the corresponding, real eigenvalue. In the above example, the simulated third factor is very slightly smaller than the "real" third factor, but nobody in their right mind is going to retain a three-factor solution here.
