Instrumental variable estimation for compositional treatments. [PDF]
Sci RepMany scientific datasets are compositional in nature. Important biological examples include species abundances in ecology, cell-type compositions derived from single-cell sequencing data, and amplicon abundance data in microbiome research.

Integrating endogeneity in survey sampling using instrumental-variable calibration estimator. [PDF]
HeliyonThe endogeneity problem arises when the auxiliary variables correlate to the error terms. In such cases, appropriate instrumental variables ensure efficient estimation.

Hospitalization Due to Fire-Induced Pollution in the Brazilian Legal Amazon from 2005 to 2018
Remote Sensing, 2021 Fire is widely used in the Amazon as a ubiquitous driver of land management and land cover change. Regardless of their purpose, fires release a considerable amount of pollutants into the atmosphere, with severe consequences for human health.

Instrumental variable analysis [PDF]
Nephrology Dialysis Transplantation, 2012 The main advantage of the randomized controlled trial (RCT) is the random assignment of treatment that prevents selection by prognosis. Nevertheless, only few RCTs can be performed given their high cost and the difficulties in conducting such studies.

Instrumental variables, local instrumental variables and control functions [PDF]
Working Paper Series, 2002 We consider the identification of the average treatment effect in models with continuous endogenous variables whose impact is heterogeneous. We derive a testable restriction that allows us to assess the degree of unobserved heterogeneity. Our analysis uses assumptions relating to the Local Instrumental Variables (LIV) approach and the control function ...

Instrumental variable regression via kernel maximum moment loss
Journal of Causal Inference, 2023 We investigate a simple objective for nonlinear instrumental variable (IV) regression based on a kernelized conditional moment restriction known as a maximum moment restriction (MMR).
