EIV

EIV is an acronym that can refer to several different concepts depending on the context. There is no single, universal definition for the term, and its meaning is typically clarified by the field or industry in which it appears.

In statistics and econometrics, EIV commonly stands for Errors-in-Variables. This term describes a class of models that account for measurement error in one or more variables used in regression analysis. When variables are measured with error, ordinary least squares estimates can be biased and inconsistent. Estimation methods for EIV include Deming regression, total least squares, and maximum likelihood approaches that specify error distributions.

In identity verification and financial services, EIV can denote Electronic Identity Verification. This process is used to confirm a person’s identity online, often as part of onboarding, fraud prevention, or regulatory compliance. EIV methods may combine document verification, knowledge-based authentication, device signals, and biometric checks, depending on the risk profile and regulatory requirements of the service provider.

Other uses of EIV exist in technology, information systems, and industry jargon. Because the acronym is not unique to one discipline, it frequently appears in product names, software modules, or project terminology where the intended meaning is defined within that specific context. When encountering EIV, clarification from the surrounding materials or stakeholders is typically necessary to determine the exact interpretation.
