Modeling within-department homogeneity in research quality rankings: an application to the Italian ISPD
Giorgio E. Montanari, Marco Doretti
In this paper, we consider the academic department ranking system of Italy, which is based on a performance index named Indice Standardizzato di Performance Dipartimentale (ISPD).…
Handling outcome-dependent missingness with binary responses: A Heckman-like model
Marco Doretti, Elena Stanghellini, Alessandro Taraborrelli
In regression models with missing outcomes, selection bias can arise when the missingness mechanism depends on the outcome itself. This proposal focuses on an extension of the Heck…
Interval identification of natural effects in the presence of outcome-related unmeasured confounding
Marco Doretti, Elena Stanghellini
With reference to a binary outcome and a binary mediator, we derive identification bounds for natural effects under a reduced set of assumptions. Specifically, no assumptions about…
Mediation analysis with case-control sampling: Identification and estimation in the presence of a binary mediator
Marco Doretti, Minna Genbäck, Elena Stanghellini
With reference to a stratified case-control procedure based on a binary variable of primary interest, we derive the expression of the distortion induced by the sampling design on t…
Path Analysis for Binary Random Variables
Martina Raggi, Elena Stanghellini, Marco Doretti
The decomposition of the overall effect of a treatment into direct and indirect effects is here investigated with reference to a recursive system of binary random variables. We sho…
Exact parametric causal mediation analysis for a binary outcome with a binary mediator
Marco Doretti, Martina Raggi, Elena Stanghellini
A parametric expression for causal natural direct and indirect effects is derived for the setting of a binary outcome with a binary mediator. The proposed effect decomposition does…
