A Guide to Statistical Adjustment: How it Really Works.

Date: May 23, 2001
Creator: U.S. Census Monitoring Board – Congressional Members
Description: Congress established the Census Monitoring Board to observe and monitor all aspects of the preparation and implementation of the 2000 decennial census. After the completion of the 200 census, many thoughtful parties continue a sincere debate over the implementation of statistical adjustment as a means of increasing the accuracy of the census and for its use in redistricting and the allocation of government funds and services. On March 1, 2001, the Census Bureau's Executive Steering Committee overseeing the post-census evaluation phase, the Accuracy and Coverage Evaluation (A.C.E.), recommended against adjusting the count. Reasonable people, including leading statisticians, have reviewed the statistical adjustment methodology and have raised legitimate questions. This report attempts to put that methodology into perspective and add to what will be further debate and discussion on how all of us as shareholders can continue to work together to ensure the most accurate census possible.

The 2010 Decennial Census: Background and Issues

The 2010 Decennial Census: Background and Issues

Date: May 24, 2010
Creator: Williams, Jennifer D.
Description: The U.S. Constitution--Article 1, Section 2, clause 3, as modified by Section 2 of the Fourteenth Amendment--requires a population census every 10 years, to serve as the basis for reapportioning seats in the House of Representatives. Decennial census data also are used for within-state redistricting and in certain formulas that determine the annual distribution of more than $400 billion dollars in federal and state funds. This report discusses the major innovations that were planned for the 2010 census, problems encountered with the attempt to automate certain census field operations, the persistent differential census undercount of less advantaged groups in the population, and efforts to ensure an equitable census.

Evaluate Habitat Use and Population Dynamics of Lampreys in Cedar Creek, 2000 Annual Report.

Evaluate Habitat Use and Population Dynamics of Lampreys in Cedar Creek, 2000 Annual Report.

Date: March 31, 2001
Creator: Stone, Jennifer
Description: Pacific lamprey (Lampetra tridentata) in the Columbia River Basin have declined to a remnant of their pre-1940s populations and the status of the western brook lamprey (L. richardsoni) is unknown. Identifying the biological and ecological factors limiting lamprey populations is critical to their recovery, but little research has been conducted on these species within the Columbia River Basin. This ongoing, multi-year study examines lamprey populations in Cedar Creek, Washington, a third-order tributary to the Lewis River. Adult (n = 40), metamorphosed (n = 116), transforming (n = 10), and ammocoete (n = 870) stages from both species were examined in 2000. Lamprey were captured using adult fish ladders, rotary screw traps, and lamprey electrofishers, and spawning ground surveys were conducted. US Forest Service level II and strategic point-specific habitat surveys were conducted to assess habitat requirements of both adult and larval lamprey. Multivariate statistics will be applied to determine relationships between abundance and habitat.

Sensitivity study on the parameters of the regional hydrology model for the Nevada nuclear waste storage investigations

Sensitivity study on the parameters of the regional hydrology model for the Nevada nuclear waste storage investigations

Date: December 31, 1979
Creator: Iman, R.L.; Davenport, J.M.; Waddell, R.K.; Stephens, H.P. & Leap, D.I.
Description: Statistical methodology has been applied to the investigation of the regional hydrologic systems of a large area encompassing the Nevada Test Site (NTS) as a part of the overall evaluation of the NTS for deep geologic disposal of nuclear waste. Statistical techniques including Latin hypercube sampling were used to perform a sensitivity analysis on a two-dimensional finite-element code of 16 geohydrologic zones used to model the regional ground-water flow system. The Latin hypercube sample has been modified to include correlations between corresponding variables from zone to zone. From the results of sensitivity analysis it was found that: (1) the ranking of the relative importance of input variables between locations within the same geohydrologic zone were similar, but not identical; and (2) inclusion of a correlation structure for input variables had a significant effect on the ranking of their relative importance. The significance of these results is discussed with respect to the hydrology of the region.

Statistical and cost-benefit enhancements to the DQO process for characterization decisions

Statistical and cost-benefit enhancements to the DQO process for characterization decisions

Date: September 12, 1996
Creator: Goodman, D.
Description: The costs of characterization can comprise a sizeable fraction of a remediation program budget. The DQO Process has been instituted at DOE to ensure that the investment in characterization adds net value to each remediation project. Thoughtful characterization can be very important to minimizing the total cost of a remediation. Strategic information gained by characterization can reduce the remediation costs by reducing the unproductive investment in unnecessary remediation of portions of a site that really don`t need to be remediated, and strategic information can reduce remediation costs by reducing the frequency of expensive rework or emergency action that result when remediation has not been pursued to the extent that really is needed.

Probabilistic and numerical techniques in the study of statistical theories of turbulence. Final Technical Report

Probabilistic and numerical techniques in the study of statistical theories of turbulence. Final Technical Report

Date: June 9, 2003
Creator: Ellis, Richard S. & Turkington, B.
Description: In this research project we made fundamental advances in a number of problems arising in statistical equilibrium theories of turbulence. Here are the highlights. In most cases the mathematical analysis was supplemented by numerical calculations. (a) Maximum entropy principles. We analyzed in a unified framework the Miller-Robert continuum model of equilibrium states in an ideal fluid and a modification of that model due to Turkington. (b) Equivalence and nonequivalence of ensembles. We gave a complete analysis of the equivalence and nonequivalence of the microcanonical, canonical, and mixed ensembles at the level of equilibrium macrostates for a large class of models of turbulence. (c) Nonlinear stability of flows. We refined the well known Arnold stability theorems by proving the nonlinear stability of steady mean flows for the quasi-geostrophic potential vorticity equation in the case when the ensembles are nonequivalent. (d) Geophysical application. The theories developed in items (a), (b), and (c) were applied to predict the emergence and persistence of coherent structures in the active weather layer of the Jovian atmosphere. This is the first work in which sophisticated statistical theories are synthesized with actual observations data from the Voyager and Galileo space missions. (e) Nonlinear dispersive waves.

Meeting report: Workshop on reduction and predictability of natural disasters

Date: April 21, 1997
Creator: Rundle, J.; Klein, W. & Turcotte, D.
Description: Natural hazards such as earthquakes and severe floods are a continual menace to large segments of the population worldwide. Recently the United Nations has focused attention on this global problem by declaring the 90`s the Decade of Natural Hazard Reduction. In addition to the obvious threat to human life natural hazards can cause severe economic hardship locally and, in an ever more complex and interactive world economy, dislocations that are felt in areas far beyond the region of a specific event. To address these concerns a workshop on Reduction and Predictability of Natural Disasters was held at the Santa Fe Institute on January 5--9, 1994. The Santa Fe Institute was originally founded in 1985 to study the emergent properties of complex nonlinear systems seen in a diversity of fields, from physical science to economics to biology. During the workshop, which brought together 25 geologists, geophysicists, hydrologists, physicists, and mathematicians, a wide variety of natural disasters and hazards were considered. These include earthquakes, landslides, floods, tsunamis, hurricanes, and tornadoes. The general them of the meeting was the application of the techniques of statistical mechanics to problems in the earth sciences.

Exploitation of parallelism in climate models. Final report

Exploitation of parallelism in climate models. Final report

Date: February 5, 2001
Creator: Baer, Ferdinand; Tribbia, Joseph J. & Williamson, David L.
Description: This final report includes details on the research accomplished by the grant entitled 'Exploitation of Parallelism in Climate Models' to the University of Maryland. The purpose of the grant was to shed light on (a) how to reconfigure the atmospheric prediction equations such that the time iteration process could be compressed by use of MPP architecture; (b) how to develop local subgrid scale models which can provide time and space dependent parameterization for a state-of-the-art climate model to minimize the scale resolution necessary for a climate model, and to utilize MPP capability to simultaneously integrate those subgrid models and their statistics; and (c) how to capitalize on the MPP architecture to study the inherent ensemble nature of the climate problem. In the process of addressing these issues, we created parallel algorithms with spectral accuracy; we developed a process for concurrent climate simulations; we established suitable model reconstructions to speed up computation; we identified and tested optimum realization statistics; we undertook a number of parameterization studies to better understand model physics; and we studied the impact of subgrid scale motions and their parameterization in atmospheric models.

Creator: Baer, F.; Tribbia, J.J. & Williamson, D.L.
Description: The US Department of Energy (DOE), through its CHAMMP initiative, hopes to develop the capability to make meaningful regional climate forecasts on time scales exceeding a decade, such capability to be based on numerical prediction type models. We propose research to contribute to each of the specific items enumerated in the CHAMMP announcement (Notice 91-3); i.e., to consider theoretical limits to prediction of climate and climate change on appropriate time scales, to develop new mathematical techniques to utilize massively parallel processors (MPP), to actually utilize MPPs as a research tool, and to develop improved representations of some processes essential to climate prediction. In particular, our goals are to: (1) Reconfigure the prediction equations such that the time iteration process can be compressed by use of MMP architecture, and to develop appropriate algorithms. (2) Develop local subgrid scale models which can provide time and space dependent parameterization for a state- of-the-art climate model to minimize the scale resolution necessary for a climate model, and to utilize MPP capability to simultaneously integrate those subgrid models and their statistics. (3) Capitalize on the MPP architecture to study the inherent ensemble nature of the climate problem. By careful choice of initial states, many realizations ...

Final technical report for Treatment of cloud radiative effects in general circulation models

Final technical report for Treatment of cloud radiative effects in general circulation models

Date: October 8, 1998
Creator: Wang, Wei-Chyung
Description: The objectives of our participation in the Atmospheric Radiation Measurement (ARM) program were (1) to improve GCM treatment of subgrid-scale variability of cloud-radiation interaction, and (2) to study the effect of variability on GCM climate simulations. Specifically, the studies focused on the development of a ''mosaic'' approach to parameterize the variability associated with cloud vertical ''geometric association'' and horizontal ''inhomogeneity''; and the evaluation and improvement of radiative effects of aerosols and layer clouds. These studies were conducted using the shortwave and longwave radiation and cloud parameterizations employed in the SUNY-Albany regional climate model and the NCAR-CCM3 global climate model. The measurements at the ARM Southern Great Plains were used to evaluate and improve these GCM parameterizations. In addition, we also used the cloud resolving model simulations to supplement the cloud statistics, in particular the cloud geometric association and vertical water/ice distribution.

IMPORTANCE OF MATERIAL BALANCES AND THEIR STATISTICAL EVALUATION IN RUSSIAN MATERIAL, PROTECTION, CONTROL AND ACCOUNTING

IMPORTANCE OF MATERIAL BALANCES AND THEIR STATISTICAL EVALUATION IN RUSSIAN MATERIAL, PROTECTION, CONTROL AND ACCOUNTING

Date: July 25, 1999
Creator: FISHBONE,L.G.
Description: While substantial work has been performed in the Russian MPC&A Program, much more needs to be done at Russian nuclear facilities to complete four necessary steps. These are (1) periodically measuring the physical inventory of nuclear material, (2) continuously measuring the flows of nuclear material, (3) using the results to close the material balance, particularly at bulk processing facilities, and (4) statistically evaluating any apparent loss of nuclear material. The periodic closing of material balances provides an objective test of the facility's system of nuclear material protection, control and accounting. The statistical evaluation using the uncertainties associated with individual measurement systems involved in the calculation of the material balance provides a fair standard for concluding whether the apparent loss of nuclear material means a diversion or whether the facility's accounting system needs improvement. In particular, if unattractive flow material at a facility is not measured well, the accounting system cannot readily detect the loss of attractive material if the latter substantially derives from the former.
