Wang L, Robins J, Richardson T
Biometrika . 2018 Mar; 104(1):229-236. PMID: 29505035
Instrumental variables are widely used for estimating causal effects in the presence of unmeasured confounding. The discrete instrumental variable model has testable implications for the law of the observed data....

Wang L, Zhou X, Richardson T
Biometrika . 2018 Feb; 104(3):597-612. PMID: 29430035
It is common in medical studies that the outcome of interest is truncated by death, meaning that a subject has died before the outcome could be measured. In this case,...

Wang L, Richardson T, Zhou X
J R Stat Soc Series B Stat Methodol . 2017 May; 79(3):719-735. PMID: 28458613
It is common that in multi-arm randomized trials, the outcome of interest is "truncated by death," meaning that it is only observed or well-defined conditioning on an intermediate outcome. In...

Am J Epidemiol . 2016 Sep; 184(7):520-531. PMID: 27651384
Recent studies suggest that epigenetic programming may mediate the relationship between early life environment, including parental socioeconomic position, and adult cardiometabolic health. However, interpreting associations between early environment and adult...
