Categorization indicates whether the test is parametric or nonparametric. Parametric tests evaluate the null hypothesis from specific data or parameters (mean, standard deviation, etc.).
WitrynaSuch parametric approaches are powerful only if the ob-served data perfectly matches with the presumed model. On the other hand, nonparametric (model-free) data-driven techniques are robust to data model mismatch, that results in wider applicability of such techniques.
