Propensity Score Matching with Limited Overlap
In this article, we have demostrated the application of two newly proposed estimators which accounts for lack of overlap under propensity score matching on a case study involing the analysis of health expenditure data for the United States.

متن کاملSleep Overlap Syndrome
Overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA), was first defined by Flenley. Although it can refer to concomitant occurrence of any of the pulmonary diseases and OSA, overlap syndrome is commonly considered as the coexistence of OSA and COPD. This disease has unique adverse health consequences distinct from ...
متن کاملRobust Matching of Aerial Images with Low Overlap
This paper addresses the problem of aerial image matching. We analyze existing approaches to this problem and show that, though the modern algorithms cope with the task quite well, their results are deteriorated in case of low overlap and significant rotation angle between the images. A two-stage feature-based image matching scheme is presented. It is shown that preliminary stage of simplified ...
متن کاملTextual Entailment Through Extended Lexical Overlap and Lexico-Semantic Matching
This paper presents two systems for textual entailment, both employing decision trees as a supervised learning algorithm. The first one is based primarily on the concept of lexical overlap, considering a bag of words similarity overlap measure to form a mapping of terms in the hypothesis to the source text. The second system is a lexicosemantic matching between the text and the hypothesis that ...
متن کاملObject Property Matching Utilizing the Overlap between Imported Ontologies
Large scale Linked Data is often based on relational databases and thereby tends to be modeled with rich object properties, specifying the exact relationship between two objects, rather than a generic is-a or part-of relationship. We study this phenomenon on government issued statistical data, where a vested interest exists in matching such object properties for data integration. We leverage th...
