Generalized empirical likelihood estimators and tests under partial weak and strong identification [PDF]
, 2005 The purpose of this paper is to describe the performance of generalized empirical likelihood (GEL) methods for time series instrumental variable models specified by nonlinear moment restrictions as in Stock and Wright (2000, Econometrica 68, 1055–1096 ...

Adding covariates to bounds: what is the question?
Journal of Causal InferenceSymbolic nonparametric bounds for partial identification of causal effects now have a long history in the causal literature. Sharp bounds, bounds that use all available information to make the range of values as narrow as possible, are often the goal ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Unitariness and Partial Identification in the Bella Coola Middle Voice
Kansas Working Papers in Linguistics, 1997 The Bella Coola suffix -m has been analyzed in the literature as two or even three separate morphemes, based on the variable effects it has on the transitivity of its base.

Parameters identification for a nonlinear partial differential equation in image denoising
Moroccan Journal of Pure and Applied Analysis, 2023 In this work and in the context of PDE constrained optimization problems, we are interested in identification of a parameter in the diffusion equation proposed in [1]. We propose to identify this parameter automatically by a gradient descent algorithm to

An evolutionary approach to the identification of Cellular Automata based on partial observations
, 2015 In this paper we consider the identification problem of Cellular Automata (CAs). The problem is defined and solved in the context of partial observations with time gaps of unknown length, i.e. pre-recorded, partial configurations of the system at certain,

Anatomy of Geodesic Witten Diagrams [PDF]
, 2017 We revisit the so-called "Geodesic Witten Diagrams" (GWDs) \cite{ScalarGWD}, proposed to be the holographic dual configuration of scalar conformal partial waves, from the perspectives of CFT operator product expansions.

Partial Identification in Two-sided Matching Models [PDF]
SSRN Electronic Journal, 2013 Abstract We propose a methodology for estimating preference parameters in matching models. Our estimator applies to repeated observations of matchings among a fixed group of individuals. Our estimator is based on the stability conditions in matching models; we consider both transferable (TU) and nontransferable utility (NTU) models ...
