Multivariate Statistical Techniques in Neuropsychology: II. Comparison of Number of Factors Rules with the Motor Scale of the Luria-Nebraska Neuropsychological Battery.
International Journal of Clinical Neuropsychology
Discusses the relative advantages of statistical rules, mathematical models, and empirical methods in deciding the appropriate number of factors to be extracted in a factor analysis. The use of these approaches is illustrated using data from 125 normals and 375 brain-damaged and psychiatric patients on the Motor scale of the Luria-Nebraska Neuropsychological Battery. It is recommended that researchers accept a slightly larger number of factors rather than omit a possibly substantive factor and that at least 2 of the following 3 rules be used: scree test, parallel analysis, and percent variance.
