Nonparametric instrumental variable (NPIV) estimation is a cutting‐edge methodological framework employed to uncover causal relationships in the presence of endogenous regressors, without imposing ...

In the usual Gauss-Markov (GM) framework of structural linear models, the GM estimators of the regression parameters become inconsistent if at least one of the ...

Giles (1982) derived the asymptotic properties of instrumental variable estimators of parameters in a linear regression model with stochastic regressors when parameters are subject to exact linear ...

Results of Phase III Randomized Trial for Use of Docetaxel as a Radiosensitizer in Patients With Head and Neck Cancer, Unsuitable for Cisplatin-Based Chemoradiation Sixty-five empirical papers were ...

Abstract: Bias due to unobserved confounding can seldom be ruled out with certainty when estimating the causal effect of a nonrandomized treatment. The instrumental variable (IV) design offers, under ...

RESULTS: Among 6,232 elderly patients, the instrumental variable estimate indicated an increase in median survival of 33 days and an improvement in 1-year survival of 9% attributable to chemotherapy.

A frequent problem in the estimation of linear regression models is that the predictors are correlated with the error term contained in the regression equation. To ...

Several of the estimation methods supported by PROC MODEL are instrumental variables methods. There is no standard method for choosing instruments for nonlinear regression. Few econometric textbooks ...

“LIKE elaborately plumed birds…we preen and strut and display our t-values.” That was Edward Leamer's uncharitable description of his profession in 1983. Mr Leamer, an economist at the University of ...
