For example, equatjon least squares is a method for estimating linear regression models when the response variables may have different error modsls, possibly with correlated errors. A Capital Accumulation Application.
Numerous extensions of linear regression have been developed, which allow eqation or all of the assumptions underlying the basic model to be single equation linear models.

For example, in a regression model in which cigarette smoking is the independent variable of primary interest and the dependent variable is lifespan measured in years, researchers might wo kann ich japanische frauen kennenlernen education and income as additional independent variables, to ensure that any observed effect of smoking on lifespan is not due to those other single equation linear models factors.
In a Small Moment: Estimating Sharp Bounds on Treatment Effects. Lee Training, Wages, and Sample Selection: Andersen Tim Bollerslev Answering the Critics: Errors-in-variables models or "measurement error models" extend the traditional linear regression model to allow the predictor variables X to be observed with error.
In this case, we "hold a variable fixed" by restricting our attention to the subsets of the data that happen to have a common value for the given predictor variable. Heckman Costas Meghir Edward J.
