It is indicated that the scree plot not be used as a stand-alone procedure in determining the number of components to retain . According to Kanyongo , researchers should therefore use it with other procedures, for example, the parallel analysis. Webb13 apr. 2024 · The number of factors that might be retained was determined using eigenvalues, parallel analysis, optimal coordinates, and acceleration factor to eliminate subjectivity in reading the scree plot. If these parameters provided opposing recommendations for the number of factors to retain, other considerations were used, …
