| ID | Year | Validation Technique | Description |
| 1 | 1999 | Machine-Aided [63] | In this technique, the multi-graph machine is used for specific purposes. |
| 2 | 2004 | Leave-one-out cross Validation [64] | This application is used to validate loss sensitive data, as well as the mathematical modeling purposes. |
| 3 | 2015 | Multistage Validation [62] | The purpose of this technique is to be able to simulate various systems. |
| 4 | 2015 | Tracing/Traceability [62] | This is a logical consistency checking technique that is used to evaluate the logical consistency of the framework/model against the domain model. |
| 5 | 2015 | Face Validity [62] | This technique was developed to make sure the model or framework is complete, logical, and useful, which is why it is important. |
| 6 | 2005 | Cross-validation [61] | It is a method for evaluating the accuracy of a model, which does not require any further examples to be examined prior to assessing the precision of the model. It is said to be also applicable to mathematical metamodeling. |
| 7 | 2021 | Comparison with other models [49] | By comparing the domain model with the metamodel, its completeness, accuracy, and correctness could be determined. |
| 8 | 2006 | Bootstrap Approach [60] | There are several advantages to bootstrapping over simulation in terms of computational efficiency. This software has been developed for the purpose of modeling simulations. |
| 9 | 2007 | Formal Ontology [65] | This method uses ontological domains as a basis for its operation. During the course, a great deal of emphasis is placed on theories. |
| 10 | 2007 | Subjective Validation [66] | The purpose of this method is to validate the framework, models, or metamodels of analog circuits. |
| 11 | 2010 | Case Study [67] | This technique is used to evaluate the processes through which metamodels are derived. |
