Evaluating the Gifted Program of an Urban School District: Using a Modified Regression Discontinuity Design — Aug 31, 2010

This paper examines the impact of a gifted program on retention in an urban school district using a regression discontinuity design.

JOURNAL ARTICLE

Power of Tests for a Dichotomous Independent Variable Measured with Error — Dec 31, 2007

Examines implications for statistical power of using predicted probabilities for a dichotomous variable rather than the actual variable. Information loss from not observing actual values can be large. Direct substitution is easy and efficient.

A Simple Identification Proof for a Mixture of Two Univariate Normal Distributions — Dec 31, 2007

A simple proof of the identification of a mixture of two univariate normal distributions is given.

Abstract

JOURNAL ARTICLE

Medicare Capitation Model, Functional Status, and Multiple Comorbidities: Model Accuracy — Dec 31, 2007

Examines financial implications of the Centers for Medicare & Medicaid Services Hierarchical Condition Categories risk-adjustment model on Medicare payments for individuals with comorbid chronic conditions. Some payments were underpredicted.

JOURNAL ARTICLE

The Sample Selection Model from a Method of Moments Perspective — Dec 31, 2006

It is shown how the usual two-step estimator for the standard sample selection model can be seen as a method of moments estimator. Furthermore, it is shown that from the MM formulation, it is straightforward to derive various specification tests, in particular tests for selection bias, equivalence with the censored regression model, normality, homoskedasticity, and exogeneity.

JOURNAL ARTICLE

Imputation of SF-12 Health Scores for Respondents with Partially Missing Data — Dec 31, 2004

Missing SF-12 items are prevalent and lead to reduced analytical power. Regression-based multi-pattern imputation using the available SF-12 items is efficient and can produce good estimates of the scores.

JOURNAL ARTICLE

Improving Care for Minorities: Can Quality Improvement Interventions Improve Care and Outcomes for Depressed Minorities? Results of a Randomized, Controlled Trial — Dec 31, 2002

Quality improvement programs appear to improve quality of care without increasing disparities, and may offer an approach to reduce health disparities.

REPORT

Effect of the Variable Reenlistment Bonus on Reenlistment Rates: Empirical Results for FY 1971 — Dec 31, 1974

A preliminary study affirming that the VRB is an effective policy tool for increasing first-term reenlistment rates.

JOURNAL ARTICLE

The Analysts' Bookshelf: Publications of The RAND Corporation — Dec 31, 1955

The purpose of this note is to indicate the general nature of the RAND Corporations unclassified operations research output and to point out where it can be examined.
