A Comprehensive Trial Of The Scree And Kg Criteria For Determining The Number Of Factors
Abstract
In most well designed researches larger substantive factors show a break in size from those of a trivial lower degree of variance, which are due to error and other sources. The only short test for the number of such factors that has been repeatedly supported by plasmode results is the scree. The present experiment extends this empirical testing of the scree by taking 15 plasmodes, which vary in (1) number of variables, (2) of factors, (3) degree of obliquity, from orthogonal cases on, (4) presence of simple structure, (5) presence of error, extending to factoring random numbers, and (6) size of communality. The results support the scree and show it superior to the Kaiser-Guttman unity root criterion. Apart from the scree itself, a brief examination is made of the reliability of its use in the hands of trained and untrained judges. A second evaluation of the intrinsic validity of the scree is made by examining internal consistency of item and parcel factoring, of different sampling of variables and of change of population. The result again supports its capacity to locate the correct number of factors within narrow limits.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
