Power Comparison of Various Normality Tests
Pakistan Journal of Statistics and Operation Research, 2015 The assumption of normality is very important because it is used in many statistical procedures such as Analysis of variance, linear regression analysis, discriminant analysis and t-tests. The three common procedures are used for assessing the assumption of normality that is graphical methods, numerical methods and formal normality tests.

Sound-power tests of a garden tractor [PDF]
The Journal of the Acoustical Society of America, 1990 Sound-power tests are being developed as noise standards, particularly in Europe. An example is the lawn mower. A detailed set of experiments was performed measuring the sound power of a garden tractor with a mower, provided by the John Deere Company.

The power of unit root tests under local-to-finite variance errors [PDF]
, 2015 We study the power of four popular unit root tests in the presence of a local-to-finite variance DGP. We characterize the asymptotic distribution of these tests under a sequence of local alternatives, considering both stationary and explosive ones .

The power of a paired t-test with a covariate [PDF]
Social Science Research, 2015 Many researchers employ the paired t-test to evaluate the mean difference between matched data points. Unfortunately, in many cases this test in inefficient. This paper reviews how to increase the precision of this test through using the mean centered independent variable x, which is familiar to researchers that use analysis of covariance (ANCOVA).
