validation
1. A process associated with the collection and production of intelligence that confirms that an intelligence collection or production requirement is sufficiently important to justify the dedication of intelligence resources, does not duplicate an existing requirement, and has not been previously satisfied. 2. A part of target development that ensures all vetted targets meet the objectives and criteria outlined in the commander’s guidance and ensures compliance with the law of armed conflict and rules of engagement. 3. In computer modeling and simulation, the process of determining the degree to which a model or simulation is an accurate representation of the real world from the perspective of the intended uses of the model or simulation. 4. Execution procedure used by combatant command components, supporting combatant commanders, and providing organizations to confirm to the supported commander and United States Transportation Command that all the information records in a time-phased force and deployment data not only are error free for automation purposes, but also accurately reflect the current status, attributes, and availability of units and requirements. See also independent review; time-phased force and deployment data; verification. (JP 3-35)

Validation
the process of determining how well one system replicates properties of some other system or, more generally, any comparison between the representation of a system and specified criteria. The validation of an operating model cannot be separated from the purpose for which it is designed and used.
the process of determining how well one system replicates properties of some other system or, more generally, any comparison between the representation of a system and specified criteria. The validation of an operating model cannot be separated from the purpose for which it is designed and used.
Validation is the process of increasing the confidence that the outputs of the model conform to reality in the required range. In some cases, the model's output can be compared to data from historical sources or from an experiment conducted for validation. A model can never be completely validated. We can never prove that its results conform to reality in all respects. It can only be invalidated. Predictive models be validated only by judgment, since a model may fit past data well without having good predictive qualities. (IIASA)

validation
Validation first removes part of the data(test dataset) and then uses the rest of the data(training dataset) to develop the trend and autocorrelation models to be used for prediction. If the prediction works for the test dataset(choice of semivariogram model, choice of lag size, choice of search neighborhood, etc), we can feel comfortable that it also works for the whole dataset.
Note: In the process of prediction, it is better for the whole sample dataset to be divided into two parts; one part with majority of the data is used for prediction and the other for verification.

Validation
The word validation has several uses:
- In general, validation is the process of checking if something satisfies a certain criterion. Examples would include checking if a statement is true (validity), if an appliance works as intended, if a computer system is secure, or if computer data are compliant with an open standard. Validation implies one is able to testify that a solution or process is correct or compliant with set standards or rules.
- In a quality management system, validation should not be confused with verification. Validation usually relates to meeting the needs of an external customer or user of a product, service, or system: Verification is usually an internal quality process of determining compliance with a regulation or specification. An easy way of recalling the difference between validation and verification is that validation is ensuring "you built the right product" and verification is ensuring "you built the product right." Verification is testing to confirm that a product complies with its requirements and specifications. Validation is testing to confirm that it satisfies stakeholder needs.
- Validation can mean to declare or make legally valid or to prove valid or confirm the validity of data, information, or processes:
- In computer terminology, validation refers to the process of data validation, controlling that data inserted into an application satisfies pre determined formats or complies with stated length and character requirements and other defined input criteria.
- In computer security, validation also refers to the process of verifying that a user or computer program is allowed to do something.
- In psychology and human communication, validation is the reciprocated communication of respect which communicates that the other's opinions are acknowledged, respected, heard, and (regardless whether or not the listener actually agrees with the content), they are being treated with genuine respect as a legitimate expression of their feelings, rather than marginalized or dismissed.
- In the pharmaceutical and biotechnology industry, validation refers to establishing documented evidence that a process or system, when operated within established parameters, can perform effectively and reproducibly to produce a medicinal product meeting its pre-determined specifications and quality attributes (from European Union Good Manufacturing Practices Guide, Annex 15). Regulatory bodies in the U.S., European Union, and Japan (amongst many others) require validation, causing it to become its own sub-industry supporting the pharmaceutical, biotechnology, and medical device industries.
- in finance, validation is a process part of the "trade life-cycle."
- Validation is important because it disallows data that can not possibly be either true or real to be entered into a database or computer system.
- Validation against an incomplete or insufficient set of criteria can lead to a state of "validated" where "validated" does not confer the confidence that the term intends. Thus validation of the validation criteria is an important aspect that is often overlooked. Establishing such validation criteria can be a very difficult task when evaluating complex systems such as Air Traffic Management systems. Establishing "fitness for purpose" is often a more useful concept to support evaluation of complex systems in that the approach focuses on involving stakeholders in establishing and reviewing the purpose that the system must satisfy as the system emerges from early design. This allows flexibility in the evaluation process as ideas turn into detailed designs. Such flexibility is essential in the early development phases in order to avoid engineering white elephants. [The European Operational Concept Validation Methodology E-OCVM provides an approach to validating complex Air Traffic Management systems by establishing fitness for purpose in a world of shifting and incomplete validation criteria]E-OCVM.
