The Central Role of the Propensity Score in Observational Studies for Causal Effects.
 Biometrika
, 1983
"... SUMMARY The propensity score is the conditional probability of assignment to a particular treatment given a vector of observed covariates. Both large and small sample theory show that adjustment for the scalar propensity score is sufficient to remove bias due to all observed covariates. Application ..."

. Applications include: (i) matched sampling on the univariate propensity score, which is a generalization of discriminant matching, (ii) multivariate adjustment by subclassification on the propensity score where the same subclasses are used to estimate treatment effects for all outcome variables and in all
Centrality estimation in large networks
 INTL. JOURNAL OF BIFURCATION AND CHAOS, SPECIAL ISSUE ON COMPLEX NETWORKS’ STRUCTURE AND DYNAMICS
, 2007
"... Centrality indices are an essential concept in network analysis. For those based on shortestpath distances the computation is at least quadratic in the number of nodes, since it usually involves solving the singlesource shortestpaths (SSSP) problem from every node. Therefore, exact computation is ..."

is infeasible for many large networks of interest today. Centrality scores can be estimated, however, from a limited number of SSSP computations. We present results from an experimental study of the quality of such estimates under various selection strategies for the source vertices.
Ethernet: Distributed packet switching for local computer networks
 COMMUN. ACM
, 1976
"... Ethernet is a branching broadcast communication system for carrying digital data packets among locally distributed computing stations. The packet transport mechanism provided by Ethernet has been used to build systems which can be viewed as either local computer networks or loosely coupled multipr ..."

multiprocessors. An Ethernet's shared communication facility, its Ether, is a passive broadcast medium with no central control. Coordination of access to the Ether for packet broadcasts is distributed among the contending transmitting stations using controlled statistical arbitration. Switching of packets
Comparison Of Centrality Estimators For Several Distributions
"... The measure of central tendency is the most commonly used tool in statistical data analysis. The ability to determine an “average ” provides a way to locate data centrality. Central tendency is usually determined by one of three methods. One can calculate the mean, median or midrange of a sample ..."

The adaptive nature of human categorization
 Psychological Review
, 1991
"... A rational model of human categorization behavior is presented that assumes that categorization reflects the derivation of optimal estimates of the probability of unseen features of objects. A Bayesian analysis is performed of what optimal estimations would be if categories formed a disjoint partiti ..."

Is information risk a determinant of asset returns
 Journal of Finance
, 2002
"... We investigate the role of informationbased trading in affecting asset returns. We show in a rational expectation example how private information affects equilibrium asset returns. Using a market microstructure model, we derive a measure of the probability of informationbased trading, and we estim ..."

estimate this measure using data for individual NYSElisted stocks for 1983 to 1998. We then incorporate our estimates into a Fama and French ~1992! assetpricing framework. Our main result is that information does affect asset prices. A difference of 10 percentage points in the probability of information
Information Retrieval as Statistical Translation
"... We propose a new probabilistic approach to information retrieval based upon the ideas and methods of statistical machine translation. The central ingredient in this approach is a statistical model of how a user might distill or "translate" a given document into a query. To assess the rele ..."

Term structure evidence on interest rate smoothing and monetary policy inertia
 FORTHCOMING IN THE JOURNAL OF MONETARY ECONOMICS
, 2001
"... Numerous studies have used quarterly data to estimate monetary policy rules or reaction functions that appear to exhibit a very slow partial adjustment of the policy interest rate. The conventional wisdom asserts that this gradual adjustment reflects a policy inertia or interest rate smoothing behav ..."

The American customer satisfaction index: Nature, purpose, and findings
 Jbwrwz/ of Mar&g/m
, 1996
"... The American Customer Satisfaction Index (ACSI) is a new type of marketbased performance measure for firms, industries, economic sectors, and national economies. The authors discuss the nature and purpose of ACSI and explain the theory underlying the ACSI model, the nationwide survey methodology u ..."

The authors find customer satisfaction to be greater for goods than for services and, in turn, greater
The Bits and Flops of the Nhop Multilateration Primitive For Node Localization Problems

Vital to the success of wireless microsensor networks is the ability of microsensors to "collectively perform sensi ..."
