A fundamental measure of treatment effect heterogeneity

values. We offer a non-parametric plug-in estimator, the targeted maximum likelihood estimator (TMLE) and the cross …-validated TMLE (CV-TMLE), to simultaneously estimate both the average and variance of the stratum-specific treatment effect function …. The CV-TMLE is preferable because it guarantees asymptotic efficiency under two conditions without needing entropy …

The causal effect of family physician program on the prevalence, screening, awareness, treatment, and control of hypertension and diabetes mellitus in an Eastern Mediterranean Regi...
Mohammadi, Neda; Alizadeh, Ahad; Moghaddam, Sahar Saeedi; … - In: BMC Public Health 23 (2023) 1, pp. --
Hypertension (HTN) and diabetes mellitus (DM) as part of non-communicable diseases are among the most common causes of death worldwide, especially in the WHO’s Eastern Mediterranean Region (EMR). The family physician program (FPP) proposed by WHO is a health strategy to provide primary health...

Bayesian Exploratory Factor Analysis
Conti, Gabriella; Frühwirth-Schnatter, Sylvia; … - 2014
This paper develops and applies a Bayesian approach to Exploratory Factor Analysis that improves on ad hoc classical approaches. Our framework relies on dedicated factor models and simultaneously determines the number of factors, the allocation of each measurement to a unique factor, and the...

The effect of identifiability on the relationship between risk attitudes and other-regarding concerns
Koukoumelis, Anastasios; Levati, M. Vittoria; Ploner, Matteo - 2013
Previous studies have shown that other-regarding concerns are weakened under risky situations. Daily experience also suggests that people care more about an identifiable than about an unidentifiable third person. We report on an experiment designed to explore whether rendering the other...

The Event-History Approach to Program Evaluation
Abbring, Jaap H. - 2006
This paper studies the event-history approach to microeconometric programevaluation. We present a mixed semi-Markov event-history model, discussits application to program evaluation, and analyze its empirical content.The results of this paper provide fundamental insights in what can be...

Learning from a piece of pie: the empirical content of Nash bargaining
Chiappori, Pierre-André; Donni, Olivier - 2006
Consider a model of bargaining, in which two players, 1 and 2, share a pie of size y. The bargaining environment is described by a set of parameters [lamda] that may affect agents' preferences over the agreement sharing, the status quo outcome, or both. The outcomes (i.e., whether an agreement...

Statistical Inverse Problems on Graphs with Application to Flow Volume Estimation in Computer Networks.
Singhal, Harsh - 2009

Solving and Testing for Regressor-Error (in)Dependence When no Instrumental Variables are Available: With New Evidence for the Effect of Education on Income
Ebbes, Peter; Wedel, Michel; Böckenholt, Ulf; … - 2005
This paper has two main contributions. Firstly, we introduce a new approach, the latent instrumental variables (LIV) method, to estimate regression coefficients consistently in a simple linear regression model where regressor-error correlations (endogeneity) are likely to be present. The LIV...
