Seminar Series
Administrative Data in Support of Policy Relevant Statistics

The Public Policy Program of the WSS, in partnership with the Federal Committee on Statistical Methodology's Subcommittee on the Statistical Uses of Administrative Records, is pleased to announce the launch of a seminar series on "Administrative Data in Support of Policy Relevant Statistics." The series will run from Fall 2008 until Spring 2009, with approximately one seminar a month. The series will focus on federal statistical uses of state- and locally-held administrative records, often in concert with survey data, including for federal program evaluation and other policy relevant applications.

Confirmed seminars will cover Medicaid undercount issues, Earned Income Tax Credit impact on employment, improving recidivism research, and outcomes of students attending the National Technical Institute for the Deaf. Seminars in the planning stages include examining Food Stamp eligibility and participation, innovations with the Quarterly Census of Employment, and others.

The first seminar will be: "Administrative Data in Support of Policy Relevant Statistics: The Medicaid Undercount Project." It will be held on November 13, 2008, in Room 8 of the BLS Conference Center. The full session abstract is provided below. Please put the first seminar on your calendar and watch this space for updated information each month. Direct any questions to Shelly Wilkie Martinez (rmartinez@omb.eop.gov) or Michael Cohen (MCohen@nas.edu).

SAS - New Extensions

The Statistical Computing Section of WSS is jointly sponsoring with the DC SAS User Group, DCSUG, two presentations by Bob Rodriguez of SAS Institute. The talks, listed below, discuss statistical graphics and a new product, SAS Stat Studio. The talks will be held on Tuesday, December 9, 2008, from 9:15 to 11:45 in the BLS Conference Center. Further details for this presentation can be found at www.dc-sug.org (from Oct 1 onwards). On that website, DCSUG is currently promoting their September 9 morning & September 24 evening meetings.

All those who plan to attend must be on WSS or DCSUG entry list or have a BLS ID.

Getting Started with ODS Statistical Graphics in SAS 9.2
Robert N. Rodriguez, SAS Institute

SAS 9.1 introduced an experimental extension to the output Delivery System (ODS), which enabled over two dozen SAS/STAT and SAS/ETS procedures to create statistical graphics as automatically as they create tables. This extension, referred to as "ODS Graphics" for short, requires minimal additional syntax, and it provides commonly needed displays for data analysis and statistical modeling, including scatter plots, histograms, and box-and-whisker plots. Many ODS features, such as styles and destination statements, apply equally to tables and graphs.

With the production release of ODS Graphics in SAS 9.2, over sixty statistical procedures have been enables to use this new functionality. New SAS/GRAPH procedures, as well as existing SAS/QC procedures, also take advantage of this functionality. Additional ODS styles for statistical work are available. You can use a new point-and-click graphics editor to make changes to graphs, such as modifying titles and annotating points. This talk explains the basics of using ODS Graphics to create and manage graphs for data exploration and statistical analysis.

An Introduction to SAS Stat Studio
Robert N. Rodriguez, SAS Institute

SAS Stat Studio 3.1 is new statistical software in SAS 9.2 that is designed to meet the needs of innovative problem solvers who are familiar with SAS/STAT or SAS/IML but need more versatility to create customized analyses. Stat Studio provides a rich programming environment that blends the flexibility of the IML matrix language with the ability to call SAS procedures as functions and create customized dynamic graphics.

With Stat Studio, you can build on your familiarity with either SAS/STAT or SAS/IML to write programs that explore data, fit models, and use linked graphics to relate the results to the data. You can move seamlessly between programming and interactive analysis. If your programs use methods that are computationally intensive, you can run them simultaneously in multiple workspaces. This talk demonstrates how Stat Studio facilitates techniques that would otherwise be difficult with traditional SAS programming.

Biographical Sketch

Bob Rodriguez joined SAS in 1983 and is currently a senior director in SAS R&D with responsibility for the development of statistical software, including SAS/STAT and SAS/QC. He received his Ph.D. in statistics from the University of North Carolina in 1977, and was a staff research scientist at General Motors Research Laboratories from 1977 until 1983. Bob is active in the American Statistical Association, where he currently serves as vice president.

Metadata Workshop Sponsored by NORC at the University of Chicago

The Next Frontier in Documenting Survey Data: What Data Producers and Archivists Need to Know about DDI, XML and SDMX

December 2, 2008
9:30am - 3:30pm EDT
4350 East West Highway Suite 800
Bethesda, MD 20814

Policymakers rely on statistical data to make good decisions. Data producers constantly strive to disseminate high quality and useful data. Recent breakthroughs in technology have made this task easier. The capture and exchange of information, namely, the effective management of metadata is now transformed by the availability of eXtensible Markup Language (XML); the Data Documentation Initiative (DDI); and the Statistical Data and Metadata Exchange Standard (SDMX). The combination of XML, DDI, and SDMX technologies provide a powerful set of tools for the management and dissemination of statistical data and documentation.

This free, 1-day workshop, sponsored by NORC at the University of Chicago, is intended for a non-technical audience and is targeted at data producers and archivists. The objectives of the workshop are twofold:

  • To provide an introduction to the basics of some emerging data documentation standards, such as the Data Documentation Initiative (DDI), eXtensible Markup Language (XML), and Statistical Data and Metadata Exchange Standard (SDMX) and
  • To encourage adoption of these emerging data documentation standards.

This metadata workshop will cover the following topics:

  • Introduction to metadata and XML
  • The case for metadata standards: benefits, challenges, and the future of metadata
  • Introduction to the Data Documentation Initiative (DDI) for the documentation of survey and administrative micro data
  • Essentials of the Statistical Data and Metadata Exchange Standard (SDMX) for the documentation of aggregate and time series data
  • DDI & SDMX interoperability and other important metadata specifications
  • Major contributors, users, tools, ongoing activities, next steps

This is a free workshop sponsored by NORC at the University of Chicago in collaboration with the Open Data Foundation.

GeoDa is thelatest incarnation in a long line of software tools developed by Dr. Luc Anselin's Spatial Analysis Laboratory (SAL) in the Department of Geography at the University of Illinois, Urbana-Champaign. It is designed to implement techniques for exploratory spatial data analysis (ESDA) on lattice data (points and polygons). The free program provides a user friendly and graphical interface to methods of descriptive spatial data analysis, such as spatial autocorrelation statistics, as well as basic spatial regression functionality. The latest version contains several new features such as a cartogram, a refined map movie, parallel coordinate plot, 3D visualization, conditional plots (and maps) and spatial regression.

SIGSTAT is the Special Interest Group in Statistics for the CPCUG, the Capital PC User Group, and WINFORMS, the Washington Institute for Operations Research Service and Management Science.

All meetings are in Room S3031, 1800 M St, NW from 12:00 to 1:00. Enter the South Tower & take the elevator to the 3rd floor to check in at the guard's desk.

First-time attendees should contact Charlie Hallahan, 202-694-5051, hallahan@ers.usda.gov, and leave their name. Directions to the building & many links of statistical interest can be found at the SIGSTAT website, http://www.cpcug.org/user/sigstat/.
