In statistics, an errors-in-variables model or a measurement error model is a regression model that accounts for measurement errors in the independent...

variables (covariates) are correlated with the error terms in a regression model. Such correlation may occur when: changes in the dependent variable change...

An error correction model (ECM) belongs to a category of multiple time series models most commonly used for data where the underlying variables have a...

complicated error structure. Deming regression is equivalent to the maximum likelihood estimation of an errors-in-variables model in which the errors for the...

In statistics, latent variables (from Latin: present participle of lateo 'lie hidden'[citation needed]) are variables that can only be inferred indirectly...

special case of errors-in-variables models. Simply put, the factor loading of a variable quantifies the extent to which the variable is related to a given...

In applied statistics, total least squares is a type of errors-in-variables regression, a least squares data modeling technique in which observational...

independent variables X i {\displaystyle X_{i}} are assumed to be free of error. This important assumption is often overlooked, although errors-in-variables models...

removing collinear variables as part of regression analysis, and doing so may constitute scientific misconduct. Including collinear variables does not reduce...

consists of selecting an appropriate functional form for the model and choosing which variables to include. For example, given personal income y {\displaystyle...

In statistics, propagation of uncertainty (or propagation of error) is the effect of variables' uncertainties (or errors, more specifically random errors)...

R2 increases as the number of variables in the model is increased (R2 is monotone increasing with the number of variables included—it will never decrease)...

In an economic model, an exogenous variable is one whose measure is determined outside the model and is imposed on the model, and an exogenous change is...

Predetermined variables are variables that were determined prior to the current period. In econometric models this implies that the current period error term is...
