John de Figueiredo: Wed@noon, Applied Stats Wkshop

by adiamond＠fas.harvard.edu

*************************************** Research Workshop in Applied Statistics *************************************** Join us this Wednesday (tomorrow, April 28) at noon, at CBRSS, the Center for Basic Research in the Social Sciences, 34 Kirkland Street, Room 22, for "The Timing, Intensity, and Composition of Interest Group Lobbying: An Analysis of Structural Policy Windows in the States" Our speaker will be John de Figueiredo of MIT's Sloan School of Management. ABSTRACT ----------- This is the first paper to statistically examine the timing of interest group lobbying. It introduces a theoretical framework based on recurring structural policy windows and argues that these types of windows should have a large effect on the intensity and timing of interest group activity. Using a new database of all lobbying expenditures in the U.S. states ranging up to 25 years, the paper conducts a number of statistical panel analyses using fixed effects. The results show interest group lobbying increases substantially during one of these recurring structural windows in particular--the budget process. Spikes in lobbying during budgeting are driven primarily by business groups. Moreover, even groups relatively unaffected by budgets lobby more intensely during legislative budgeting, consistent with the theory that these interests are attempting to have legislators attach (de)regulatory riders to the budget bills. Other characteristics of the legislatures, such as rules regarding disclosure laws, term limits, and electoral factors show little statistical impact on lobbying by interest groups. Overall, the paper argues that these structural policy windows largely determine lobbying expenditures on the margin. As always, lunch will be provided.

It is intended as a tour of Harvard's statistical innovations and applications with weekly stops in different disciplines such as economics, epidemiology, medicine, political science, psychology, public policy, public health, sociology and statistics. The topics of papers presented in previous years included missing data, survey analysis, Bayesian simulation, sample selection, and models for election and portfolio choice. Faculty and student participants in the workshop present their current projects, and guest speakers also give occasional presentations. The workshop provides an excellent opportunity for informal interaction between graduate students and faculty from a variety of disciplines. Course credit is available for students as either an upper-level Government or Sociology class. Lunch is provided. If you are interested, note that all events are held at noon, in Room 22, Center for Basic Research in Social Sciences (CBRSS, 34 Kirkland St., this is the yellow building across the street from William James Hall).

Bioterror Localization/Detection: Wed@noon, Appld Stats Wkshop

by adiamond＠fas.harvard.edu

*************************************** Research Workshop in Applied Statistics *************************************** Join us this Wednesday (April 21) at noon, at CBRSS, the Center for Basic Research in the Social Sciences, 34 Kirkland Street, Room 22, for "BACTrack: A System for Rapid Detection and Spatio-Temporal Localization of Biological Agent Attacks" Our speaker will be Ronald Hoffeld of MIT's Lincoln Laboratories. ABSTRACT Syndromic surveillance systems can generally be improved by inclusion of patient location information. This information is difficult to obtain from health care providers due to HIPAA privacy restrictions. Recent trends in location-based cell phone services indicate that the location histories of phone subscribers may become available on a voluntary basis. Coupling these data with individuals self-reported coarse health status (i.e. sick or healthy) suggests a new health surveillance technique. This technique, which we call BACTrack for Biological Agent Correlation Tracker, searches for spatial temporal regions in which a larger than expected percentage of the population became infected. The unique aspect of this search is that it uses current health status information with past location history data. This talk will give the results of a study we conducted to determine the operating characteristics of this detection technique. Included will be a description of the system concept, implementation approaches, detection algorithms, and estimates of performance. ----------- As always, lunch will be provided.

Sharon-Lise T. Normand: Wed/noon, Applied Stats Workshop

by Alexis J. Diamond

*************************************** Research Workshop in Applied Statistics *************************************** Join us this Wednesday (April 14) at noon, at CBRSS, the Center for Basic Research in the Social Sciences, 34 Kirkland Street, Room 22, for Statistical Models for Health Care Quality Surveillance and Public Reporting Sharon-Lise T. Normand Professor of Health Care Policy (Biostatistics) Department of Health Care Policy, Harvard Medical School Department of Biostatistics, Harvard School of Public Health Monitoring health care quality involves collection of medical data in order to identify trends and disparities in medical care delivery. In the absence of randomization, detailed medical record data have often served as the gold-standard for balancing the distribution of observations (e.g., patients) across units (e.g., states). Administrative claims data are a cheaper alternative to medical record data but have been criticized as too coarse. The question is how valid are the administrative data for monitoring health care quality. To answer this, we consider an analysis of I units, each of which involves an adjusted outcome. In the ith unit, we denote the true association between the outcome and the risk factors using the medical chart data by theta_i(X), the true association between the outcome and the risk factors using administrative data by gamma_i(Z), and assume we have estimates of each available. Within unit i, the estimated association parameters are jointly normally distributed such that conditional on gamma_i(Z), a simple linear relationship exists between theta_i(X) and gamma_i(Z). We illustrate methods to examine the value of administrative data for monitoring state-specific 30-day mortality rates after a heart attack. Preliminary results for monitoring hospital-specific rates will also be discussed. Key Words: Bayesian inference; hierarchical model; surrogacy; acute myocardial infarction; quality of care; surveillance. As always, lunch will be provided.
