As health care reform expands the use of "report cards" to grade health care providers, greater attention to reporting methods may be needed to assure the quality of such efforts.

The methods employed, as well as those recommended for future studies, are applicable to any law enforcement agency interested in attracting and identifying high-quality applicants more efficiently.

Extends the "actionable hot spot" methodology, first developed by RAND to identify likely areas for improvised explosive device emplacement, to other problem areas where policymakers are faced with spatial, temporal, and quantity constraints when deploying scarce resources. Case studies describe its application to public health, countering piracy, and fighting neighborhood crime.

We develop the "generalized persistence" (GP) model, a Bayesian multivariate model for estimating teacher effects that accommodates longitudinal data that are not vertically scaled by allowing less than perfect correlation of a teacher's effects across test administrations.

<p>Explains the relationship between reliability measurement and misclassification for physician quality and cost measures in health care. Provides details and a practical method to calculate reliability and misclassification from the data typically available to health plans. For any newly proposed system, these methods should enable an evaluator to calculate the reliabilities and, consequently, the misclassification probabilities.</p>

Failing to incorporate dependence on prior event history in subsequent relapse risk in Markov models can bias modeling results, overestimating the impact of prevention and treatment by up to 85% or underestimating the impact by up to 20%.

<p>Using a discrete time semi-Markov model, the authors develop an algorithm for nonparametric estimation of the distribution functions of sojourn times in a J state progressive disease model.</p>

Interview time in personal network studies can be reduced by randomly sampling a smaller set of the alters named by the respondent and simulating the error that results when data are collected from the smaller group.

<p>This report documents the results obtained from the re-estimation of models apportioning travel to destination area types, distance band and travel mode for an important component of the UK National Travel Model (NTM).</p>

<p>As part of a broader research effort examining officer education and development in joint matters, the authors use data analysis and complex modeling to identify billets that that provide and/or require joint experience; and determine whether there are sufficient numbers of officers with joint experience to fill such billets.</p>

<p>Previous studies have demonstrated both large gains in efficiency and reductions in bias by incorporating population information in regression estimation with sample survey data.</p>

<p>The extent to which retail clinics provide access to care for underserved populations remains largely unknown. The purpose of this study was to determine whether retail clinics tend to be located in census tracts with higher medical need.</p>

<p>The authors consider situations in which externally observable characteristics allow experts to quickly categorize individual households as likely or unlikely to contain a member of a rare target population.</p>

<p>Evaluates the feasibility and success of a new interactive elicitation methodology for collecting probabilistic expectations in a developing country context with low levels of literacy and numeracy,</p>

<p>Substance abuse treatment research is complicated by the pervasive problem of non-ignorable missing data-i.e. the occurrence of the missing data is related to the unobserved outcomes. Missing data frequently arise due to early client departure from treatment. Pattern-mixture models (PMMs) are often employed in such situations to jointly model the outcome and the missing data mechanism.</p>

<p>Cross-sectional descriptive study describes characteristics of retail clinics, including their location, scope of practice, prices, acceptance of insurance, and ownership, and to estimate the proportion of the U.S. population that lives within a short driving distance of such a clinic.</p>

<p>The authors studied the feasibility of using an internet-based panel survey to obtain timely and accurate population-based data on influenza vaccination.</p>

<p>Contrary to previous conclusions, the authors find that respondents do not tend to overweight private information when updating beliefs.</p>

<p>Commercial health plans need member racial/ethnic information to address disparities, but often lack it. We incorporate the U.S. Census Bureaugass latest surname list into a previous Bayesian method that integrates surname and geocoded information to better impute self-reported race/ethnicity.</p>
