An Empirical Test of the Utility of the Observations-To-Variables Ratio in Factor and Components Analysis

Open access
Arrindell, Willem A., van der Ende, Jan·1985·Applied Psychological Measurement

Abstract

Many researchers have proposed a minimum ratio of observations to variables or an absolute minimum of observations in order to obtain stable factor config urations. However, hardly any empirical studies em ploying real data are available that attest to the tena bility of these proposals. A systematic analysis of the problem was undertaken, using self-report data from two large phobic samples on the Fear Survey Sched ule-III (N = 1104) and the Fear Questionnaire ( N = 960). The data sets were randomly split into subsam ples with ratios varying from 1.3:1 to 19.8:1. Neither the observations to variables ratio nor an absolute minimum of observations had any influence on factor stability.

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.
