Error

Error is the lack of ability in explaining empirical phenomena. It can be classified in many ways,depending on the context. In human behavior, it could be considered an unintentional deviation from a desired aim. In measurement issues, the main distinction is between random and sistematic errors. In a statistical sense, it could be viewed either as a result of a measurement process – usually represented as a stochastic process – or as a lack of information about the data generation process. In applied sciences, modeling the error is a relevant source of knowledge and, generally, one of the main aims is to measure or control it
