TL;DR: In this article, the results of an extensive simulation study investigating the power of the Geary's test for normality are summarized, showing that it still has good power properties and that its computational simplicity makes it still a possibly useful test.
Abstract: SUMMARY The results of an extensive simulation study investigating the power of Geary's a test for normality are summarized. While there appears to be no specific situation where Geary's test clearly and for practical purposes dominates all other tests of normality, it still has good power properties. This coupled with its computational simplicity make it still a possibly useful test.

TL;DR: It is indicated that body weight and not glucose dose significantly affected disposal rates calculated from the simple exponential model, and this finding has particular significance for the current study because the weight distribution of the two groups were at variance.
Abstract: Two large groups of randomly selected women were given standard rapid intravenous glucose tolerance tests during 3rd trimester pregnancy. One group was given a 25 g, and the other a 37½ g glucose challenge. The higher dose augmented the peak value and prolonged the fall to equilibrium levels. Significantly different disposal rates resulted when the simple exponential, but not when an incremental model, was applied to the data. The source of the disagreement with different analytic models was clarified by a two-way analysis of variance which indicated that body weight and not glucose dose significantly affected disposal rates calculated from the simple exponential model. This finding has particular significance for the current study because the weight distribution of the two groups were at variance. The model using increments above a theoretic post-test leveling was found to give k rates for the two dose schedules which were not significantly different, and were also shown to be independent of the...
