15 صفحه اولInstrumental Variables Regression with Measurement Errors and Multicollinearity in Instruments
In this paper we obtain a consistent estimator when there exist some measurement errors and multicollinearity in the instrumental variables in a two stage least square estimation of parameters. We investigate the asymptotic distribution of the proposed estimator and discuss its properties using some theoretical proofs and a simulation study. A real numerical application is also provided for mor...
متن کاملUse of allele scores as instrumental variables for Mendelian randomization
BACKGROUND An allele score is a single variable summarizing multiple genetic variants associated with a risk factor. It is calculated as the total number of risk factor-increasing alleles for an individual (unweighted score), or the sum of weights for each allele corresponding to estimated genetic effect sizes (weighted score). An allele score can be used in a Mendelian randomization analysis t...
متن کاملInstrumental Variables Before and LATEr
The modern formulation of the instrumental variable methods initiated the valuable interactions between economics and statistics literatures of causal inference and fueled new innovations of the idea. It helped resolving the long-standing confusion that the statisticians used to have on the method, and encouraged the economists to rethink how to make use of instrumental variables in policy anal...
متن کاملEndogenous Regressors and Instrumental Variables
This is a more serious departure from the assumptions of the classical linear model than was the case for the Generalized Regression model, which maintained E("jX) = 0 but permitted nonconstant variances and/or nonzero correlations across error terms. Unlike the Generalized Regression model, the classical least squares estimator will be inconsistent for if the errors are correlated with the reg...
