The classic Holzinger and Swineford (1939) dataset consists of mental
ability test scores of seventh- and eighth-grade children from two
different schools (Pasteur and Grant-White). In the original dataset
(available in the MBESS
package), there are scores for 26 tests.
However, a smaller subset with 9 variables is more widely used in the
literature (for example in Joreskog's 1969 paper, which also uses the 145
subjects from the Grant-White school only).
