Scree plot with parallel analysis
WebbThe parallel analysis is computed as: n_ {parallel} = \sum_ {i} (\lambda_ {i} \ge LS_i). nparallel =∑i(λi ≥LS i). The acceleration factor ( AF AF) corresponds to a numerical solution to the elbow of the scree plot: n_ {AF} \equiv \ If \ \left [ (\lambda_ {i} \ge LS_i) \ and \ max (AF_i) \right]. nAF ≡ I f [(λi ≥ LS i) and max(AF i)]. Webb19 okt. 2016 · principal axis factoring with Oblimin rotations was carried out. We attempted four and three-factor solutions. Both the Kaiser rule of eigenvalues greater than 1 and the scree plot (see Fig. 1) indicated that three-factor solution would fit the data the best and then they show a typical scree plot.
