Stability reliability (sometimes called test, re-test reliability) is the agreement of measuring instruments over time. These two concepts go hand in hand during research and contribute to the credibility of the investigation. This indicates that the assessment checklist has low inter-rater reliability (for example, because the criteria are too subjective).

Nicolas is passionate about helping students at all levels. Repeatability or test-retest reliability is defined as 'closeness of the agreement between the results of successive measurements of the same measure and carried out under the same conditions' ( Taylor and Kuyatt, 1994, 14), which is guaranteed for any deterministic DL model.
