Variance estimation for the instrumental variables approach to measurement error in generalized linear models [PDF]

open access: yes
This paper derives and gives explicit formulas for a derived sandwich variance estimate. This variance estimate is appropriate for generalized linear additive measurement error models fitted using instrumental variables.
