We used instrumental-variable regression with a genetic instrument (Mendelian randomization) to examine a causal role of increased glucose concentrations in the development of depressive symptoms.Wesolowska, KarolinaElovainio, MarkoHintsa, TainaJokela, MarkusPulkki-Raback, LauraPitkanen, NiinaLipsanen, ...
Summary This note shows that adding monotonicity or convexity constraints on the regression function does not restore well-posedness in nonparametric instrumental variable regression. The minimum distance problem without regularization is still locally ill-posed.关键词: Ill‐posed inverse problems Instrumental...

作者: R. L. Carter and Wayne A. Fuller 摘要: Alternative instrumental variable estimators for the slope in the simple errors-in-variables model are discussed. The maximum likelihood estimator is derived for the model in which the error covariance is known to be zero and for the model in ...
