Looking for statistical stability: a new method of evaluating reliability of statistical tests.
A new method of looking for statistical reliability, stability calculation, is described and is applied to statistical tests. Alike the power of statistical tests, stability calculation enables us to assess reliability of the latter. It belongs to the category of subsampling techniques that require using subsamples taken from the original sample. It provides descriptive and non-inferential results indicating the stability percentage: the percentage of sample elements to be removed, in order to change results obtained with the original sample. The higher is the stability percentage the more reliable is the statistical test. Stability percentage and power are correlated. Stability calculation provides informations about the elements in the sample, the most powerful points.
