Is network meta-analysis as valid as standard pairwise meta-analysis? It all depends on the distribution of effect modifiers
Jansen, Jeroen P.; Naci, Huseyin - London School of Economics (LSE) - 2013
Background In the last decade, network meta-analysis of randomized controlled trials has been introduced as an extension of pairwise meta-analysis. The advantage of network meta-analysis over standard pairwise meta-analysis is that it facilitates indirect comparisons of multiple interventions...

Methodological Considerations in Cost-Effectiveness Analysis
Alemayehu, Demissie - International Institute of Social and Economic Sciences - 2014
In decision making regarding optimal resource allocation to safeguard public health, policymakers and healthcare providers rely on the availability and reliability of data about the relative costs and benefits of competing treatment options. One such an approach is based on cost effectiveness...

The causal effect of family physician program on the prevalence, screening, awareness, treatment, and control of hypertension and diabetes mellitus in an Eastern Mediterranean Region: a causal difference-in-differences analysis
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...

Semi-Parametric Estimation and Inference for the Mean Outcome of the Single Time-Point Intervention in a Causally Connected Population
Sofrygin, Oleg; van der Laan, Mark J. - In: Journal of Causal Inference 5 (2016) 1
recent methodological advances in the field of targeted maximum likelihood estimation (TMLE) and describe an estimation …-generating distribution. With this key insight in mind, we describe the TMLE for possibly-dependent units as an iid data algorithm and we …

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 pricing kernel under proportional ambiguity
Spengemann, Marco - 2025
The pricing kernel is an important tool for understanding asset prices, expected returns, and investor preferences. However, empirical findings often reveal deviations from theoretical predictions, leading to the so-called "pricing kernel puzzle". This article explores the pricing kernel under...

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
context.First, we study the problem of identifiability of joint distribution of flow volumes in a computer network from …)dependence between flow-volumes. We provide sufficient, sometimes necessary, conditions for the identifiability of the flow volumes …

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...
