Sensitivity analysis for mistakenly adjusting for mediators in estimating total effect in observational studies. [PDF]

open access: yesBMJ Open, 2017
Objectives In observational studies, epidemiologists often attempt to estimate the total effect of an exposure on an outcome of interest. However, when the underlying diagram is unknown and limited knowledge is available, dissecting bias performances is ...

When the test of mediation is more powerful than the test of the total effect. [PDF]

open access: yesBehav Res Methods, 2015
Although previous research has studied power in mediation models, the extent to which the inclusion of a mediator will increase power has not been investigated.

A three-way decomposition of a total effect into direct, indirect, and interactive effects. [PDF]

open access: yesEpidemiology, 2013
Recent theory in causal inference has provided concepts for mediation analysis and effect decomposition that allow one to decompose a total effect into a direct and an indirect effect.

Estimating the total treatment effect in randomized experiments with unknown network structure [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2022
Significance In many domains, we want to estimate the total treatment effect (TTE) in situations where we suspect network interference is present. However, we often cannot measure the network or the implied dependency structure. Surprisingly, we are able

Estimating causal effects in the presence of competing events using regression standardisation with the Stata command standsurv

open access: yesBMC Medical Research Methodology, 2022
Background When interested in a time-to-event outcome, competing events that prevent the occurrence of the event of interest may be present. In the presence of competing events, various estimands have been suggested for defining the causal effect of ...

Simulation of Total Ionizing Dose Effects Technique for CMOS Inverter Circuit

open access: yesMicromachines, 2023
The total ionizing dose (TID) effect significantly impacts the electrical parameters of fully depleted silicon on insulator (FDSOI) devices and even invalidates the on–off function of devices.

Quantifying the total effect of edge interventions in discrete multistate networks [PDF]

open access: yesat - Automatisierungstechnik, 2019
Developing efficient computational methods to assess the impact of external interventions on the dynamics of a network model is an important problem in systems biology. This paper focuses on quantifying the global changes that result from the application
