The scree test for the number of factors

Webb12 apr. 2016 · April 12, 2016. As discussed on page 308 and illustrated on page 312 of Schmitt (2011), a first essential step in Factor Analysis is to determine the appropriate number of factors with Parallel Analysis in R. The data consists of 26 psychological tests administered by Holzinger and Swineford (1939) to 145 students and has been used by … WebbI recommend the scree plot approach (or the Cattell-Nelson-Gorsuch modified scree test that uses more quantifiable values to find the bend in the plot ; Gorsuch, 1966; Gorsuch, 1983) because of its ease of use, its general accuracy in identifying the correct number of factors, and its fairly broad acceptance.
