RAND Research Topic: Statistical Analysis Methodology2014-09-01T20:43:22ZCopyright (c) 2014, The RAND CorporationRAND Corporationhttp://www.rand.org/topics/statistical-analysis-methodology.htmlExamining the Presidential Election With a Different Kind of Pollhttp://www.rand.org/blog/2012/09/examining-the-presidential-election-with-a-different.htmlSep 7, 2012Sep 7, 2012RAND is introducing a new method of forecasting the outcomes of U.S. Presidential elections. Rather than repeatedly poll new random samples, this poll uses panel of 3,500 people who are asked the same questions every week. The results illustrate the effects of election season variables.Susan Paddock Named Fellow of the American Statistical Associationhttp://www.rand.org/blog/2013/07/paddock-named-fellow-of-the-american-statistical-association.htmlJul 1, 2013Jul 1, 2013The American Statistical Association named Susan Paddock as a 2013 ASA Fellow. She was honored for excellence in statistical applications to public policy research, for integrating innovative statistical methodology with substantive problems of national healthcare policy, and for noteworthy service to the profession. Economic Development Not the Only Influence on Personal Car Usehttp://www.rand.org/news/press/2014/07/18.htmlJul 18, 2014Jul 18, 2014Although countries with high levels of economic development generally have more personal automobile travel than less-affluent nations, income is not the only factor that determines a nation's demand for cars.Introduction to Matrix Analysishttp://www.rand.org/pubs/commercial_books/CB142.htmlDec 31, 1994Dec 31, 1994Written in lucid, concise terms, this volume covers all the key aspects of matrix analysis and presents a variety of fundamental methods.Games of Strategy: Theory and Applicationshttp://www.rand.org/pubs/commercial_books/CB149-1.htmlOct 8, 2007Oct 8, 2007<p>Classic work from 1961 discusses basic concepts of game theory and its applications for military, economic, and political problems, as well as its usefulness in decisionmaking in business, operations research, and behavioral science. </p>
Public Policy and Statistics: Case Studies from RANDhttp://www.rand.org/pubs/commercial_books/CB391.htmlDec 31, 1999Dec 31, 1999This casebook describes the varied analytical techniques and substantive applications that typify how statistical thinking has been applied at RAND over the past two decades.Some Significance Tests for the Median Which Are Valid Under Very General Conditionshttp://www.rand.org/pubs/external_publications/EP19490301.htmlFeb 28, 1949Feb 28, 1949Order statistics are used to derive significance tests for the population median which are valid under very general conditions. These tests are approximately as powerful as the student t-test for small samples from a normal population. Also the application of a test requires very little computation. Thus the tests derived compare very favorably with the t-test for small sets of observations.On the Range-Midrange Test and Some Tests with Bounded Significance Levelshttp://www.rand.org/pubs/external_publications/EP19490601.htmlMay 31, 1949May 31, 1949This paper is divided into two parts. The significance tests investigated in Part I concern the population mean and are based on the quantity [(sample midrange)-(hypothetical mean)]/(sample range). The case in which the observations are a sample from a normal population is considered in detail. The tests investigated are summarized.Applications of Some Significance Tests for the Median Which Are Valid Under Very General Conditionshttp://www.rand.org/pubs/external_publications/EP19490901.htmlJan 8, 1949Jan 8, 1949Order statistics were used to derive some tests for population median which have significance levels either exact or bounded under general conditions.Large-sample Tests and Confidence Intervals for Mortality Rateshttp://www.rand.org/pubs/external_publications/EP19500601.htmlDec 31, 1949Dec 31, 1949<p>A presentation of methods which determine some valid large sample tests and confidence intervals for the mortality rate.</p>A Large Sample T-Statistic Which Is Insensitive to Non-Randomnesshttp://www.rand.org/pubs/external_publications/EP19510301.htmlDec 31, 1950Dec 31, 1950<p>Most of the well known significance tests and confidence intervals for the population mean are based on the assumption of a random sample. This paper considers how the significance levels and confidence coefficients of the commonly used class of tests and intervals based on the standard Student t-statistic are changed when the random sample requirement is violated and the number of observations is large.</p>The Logical Principles of a New Kind of Binary Counterhttp://www.rand.org/pubs/external_publications/EP19531001.htmlDec 31, 1952Dec 31, 1952<p>In a shifting register or binary counter, there is a real logical requirement for a short term or temporary storage facility.</p>On a Generalization of Classical Probability Theory, I.: Markoff Chainshttp://www.rand.org/pubs/external_publications/EP19531002.htmlDec 31, 1952Dec 31, 1952<p>The purpose of this paper is to present a further extension of the concept of a probability.</p>On the Order of Convergence of Solutions of a Difference Equation to a Solution of the Diffusion Equationhttp://www.rand.org/pubs/external_publications/EP19531201.htmlDec 31, 1952Dec 31, 1952<p>The authors treated a special differential equation with very simple boundary conditions and considered one of many possible difference equations. The results may give an indication of the kind of results to be expected with more complicated problems.</p>On the Convergence of a Solution of a Difference Equation to a Solution of the Equation of Diffusionhttp://www.rand.org/pubs/external_publications/EP19540201.htmlDec 31, 1953Dec 31, 1953<p>The authors investigate how solutions of a sequence of difference equations converge.</p>Calculation of the Resonant Properties of Electrical Cavitieshttp://www.rand.org/pubs/external_publications/EP19540301.htmlDec 31, 1953Dec 31, 1953<p>It is shown that the resonant properties of axially symmetric cavities can be calculated using data obtained on an analogous static system in an electrolytic tank.</p>Problem of Overlapping Lines in the Theory of Pressure Broadeninghttp://www.rand.org/pubs/external_publications/EP19580701.htmlDec 31, 1957Dec 31, 1957<p>The theory of pressure broadening is re-examined, in order to include the possibility of overlapping lines, which are a regular feature of pressure broadening in an ionized gas.</p>General Impact Theory of Pressure Broadeninghttp://www.rand.org/pubs/external_publications/EP19581101.htmlDec 31, 1957Dec 31, 1957<p>The work of two previous papers is extended and a theory of pressure broadening is developed which treats the perturbers quantum mechanically and allows for inelastic collisions, degeneracy, and overlapping lines. The impact approximation is used.</p>Homicides and Suicides of World War II: A Critical Analysis of 656 Homicides and 1179 Suicideshttp://www.rand.org/pubs/external_publications/EP19600101.htmlDec 31, 1959Dec 31, 1959<p>This study demonstrated that military homicides and suicides tended to conform to certain patterns resembling in many respects those of civilian groups.</p>On Relevance, Probabilistic Indexing and Information Retrievalhttp://www.rand.org/pubs/external_publications/EP19600702.htmlDec 31, 1959Dec 31, 1959<p>This paper reports on a novel technique for literature indexing and searching in a mechanized library system.</p>
