Doubly robust estimation of the local average treatment effect curve
(Wiley Blackwell Publishing, Inc, 2015-03)
We consider estimation of the causal effect of a binary treatment on an outcome, conditionally on covariates, from observational studies or natural experiments in which there is a binary instrument for treatment. We describe ...
The effect of the Mediterranean Diet on lifespan: A treatment-effect survival analysis of a population-based prospective cohort study in Southern Italy
(2021-02-01)
Background: The Mediterranean diet (MedDiet) is associated with good health. We aimed to estimate the effect of levels of adherence to the MedDiet on lifespan by performing treatment effects survival analysis. Methods: A ...
Efficient estimation of data combination models by the method of Auxiliary-to-Study Tilting (AST)
(Amer Statistical Assoc, 2016-04-02)
We propose a locally efficient estimator for a class of semiparametric data combination problems. A leading estimand in this class is the average treatment effect on the treated (ATT). Data combination problems are related ...

Effect of cold plasma treatment on mechanical properties of PET/PMMA composites
(Elsevier B.V., 2005-01-01)
Mechanical strength of polyethylene terephthalate (PET) fibres and polymethyl methacrylate (PMMA) matrix composites were studied with particular interest on the effects of oxygen and argon plasma treated fibres. PET. fibres ...
Tensile strength of radio frequency cold plasma treated PET fibers - Part 1: Influence of environment and treatment time
(Asm International, 2002-12-01)
This article reports on a series of experiments with polyethylene terepthalate (PET) treated in a radio frequency plasma reactor using argon and oxygen as a gas fuel, for treatment times equal to 5 s, 20 s, 30 s, and 100 ...

Effect of acid-methanol treatment on the physicochemical and structural characteristics of cassava and maize starches
(Wiley-Blackwell, 2008-08-01)
Physicochemical, structural and morphological characteristics of maize and cassava starches treated with 0.36% concentrated HCl in anhydrous methanol at WC for 1-8 h were analyzed and compared. Average yield of modified ...

Matching estimators with few treated and many control observations
(2018-09)
We analyze the properties of matching estimators when there are few treated, but many control observations. We show that, under standard assumptions, the nearest neighbor matching estimator for the average treatment effect ...
