Improving Reading Skills by Encouraging Children to Read in School:A Randomized Evaluation of the Sa Aklat Sisikat Reading Program in the Philippines
Reading Skills Encouraging Children Randomized Evaluation Sa Aklat Sisikat Philippines
2016/3/3
We show that a short-term (31-day) reading program, designed to provide age-appropriate reading material, to train teachers in their use, and to support teachers’ initial efforts for about a month, im...
Obesity,Weight Loss,and Employment Prospects:Evidence from a Randomized Trial
Obesity Weight Loss Employment Prospects Randomized Trial
2016/3/3
This study presents credible estimates for the causal effect of BMI growth on employment among the obese. By exploring random assignment of a weight-loss intervention based on monetary rewards, I prov...
Peer Effects in Disadvantaged Primary Schools Evidence from a Randomized Experiment
Disadvantaged Primary Schools Randomized Experiment
2016/3/2
Using data from a well- executed randomized experiment, we fi nd that the
average classroom peer achievement adversely infl uences own student
achievement in math and reading in primar...
Best (but oft-forgotten) practices: sensitivity analyses in randomized controlled trials
analysis commentary sensitivity statistics tutorial
2018/11/23
Arandomized controlled clinical trial is the best way to minimize bias in ascertaining treatment effects, but the credibility of the results of a trial depends on the validity of the methods used to a...
Analysis and Optimization of Randomized Gossip Algorithms
Analysis Optimization Randomized Gossip Algorithms
2015/7/10
We study the distributed averaging problem on an arbitrary network with a gossip constraint, which means that no node communicates with more than one neighbour in every time slot. We consider algorith...
Estimating treatment effect heterogeneity in randomized program evaluation
Causal inference individualized treatment rules LASSO moderation variable selection
2013/6/14
When evaluating the efficacy of social programs and medical treatments using randomized experiments, the estimated overall average causal effect alone is often of limited value and the researchers mus...
On the Complexity Analysis of Randomized Block-Coordinate Descent Methods
Randomized block-coordinate descent accelerated coordinate descent iteration complexity convergence rate composite minimization
2013/6/17
In this paper we analyze the randomized block-coordinate descent (RBCD) methods proposed in [8,11] for minimizing the sum of a smooth convex function and a block-separable convex function. In particul...
Respondent privacy and estimation efficiency in randomized response surveys for discrete-valued sensitive variables
Jeopardy measure numerical stigmatizing variable revealing probability
2013/4/28
In some socio-economic surveys, data are collected on sensitive or stigmatizing issues such as tax evasion, criminal conviction, drug use, etc. In such surveys, direct questioning of respondents is no...
Explaining temporal trends in annualized relapse rates in placebo groups of randomized controlled trials in relapsing multiple sclerosis: systematic review and meta-regression
multiple sclerosis relapses annualized relapse rates placebo baseline characteristics eligibility criteria meta-analysis meta-regression systematic review
2013/4/27
Background: Recent studies have shown a decrease in annualised relapse rates (ARRs) in placebo groups of randomised controlled trials (RCTs) in relapsing multiple sclerosis (RMS).
Methods: We conduc...
Iteration Complexity of Randomized Block-Coordinate Descent Methods for Minimizing a Composite Function
Block coordinate descent iteration complexity composite minimization
2011/7/19
In this paper we develop a randomized block-coordinate descent method for minimizing the sum of a smooth and a simple nonsmooth block-separable convex function and prove that it obtains an $\epsilon$-...
Efficient Online Learning via Randomized Rounding
Efficient Online Learning Randomized Rounding
2011/7/6
Most online algorithms used in machine learning today are based on variants of mirror descent or follow-the-leader.
Randomized algorithms for statistical image analysis and site percolation on square lattices
Image analysis signal detection percolation image reconstruction noisy image
2011/3/24
We propose a novel probabilistic method for detection of objects in noisy images. The method uses results from percolation and random graph theories. We present an algorithm that allows to detect obje...
Improving pneumonia case-management in Benin: a randomized trial of a multi-faceted intervention to support health worker adherence to Integrated Management of Childhood Illness guidelines
pneumonia case-management Benin randomized trial multi-faceted intervention health worker adherence Childhood Illness guidelines
2009/11/13
Integrated Management of Childhood Illness training was useful, but
insufficient, to achieve high-quality pneumonia case management. Our study
supports led to additional improve...
Princing European options on instruments with a constant dividend yield:The randomized discrete-time approach
Option pricing dividends randomization alternative models
2009/9/21
Due to the well-known fact that market returns are not
normally distributed, we use generalized hyperbolic distributions for
pricing options in a randomized discrete-time setup. The obtained
formul...
