Examples Of L 2 -Complete And Boundedly-Complete Distributions, Donald W.K. Andrews

Cowles Foundation Discussion Papers

Completeness and bounded-completeness conditions are used increasingly in econometrics to obtain nonparametric identification in a variety of models from nonparametric instrumental variable regression to non-classical measurement error models. However, distributions that are known to be complete or boundedly complete are somewhat scarce. In this paper, we consider an L 2 -completeness condition that lies between completeness and bounded completeness. We construct broad (nonparametric) classes of distributions that are L 2 -complete and boundedly complete. The distributions can have any marginal distributions and a wide range of strengths of dependence. Examples of L 2 -incomplete distributions also are provided.

Dynamic Strategic Information Transmission, Mikhail Golosov, Vasiliki Skreta, Aleh Tsyvinski, Andrea Wilson

Cowles Foundation Discussion Papers

This paper studies strategic information transmission in a dynamic environment where, each period, a privately informed expert sends a message and a decision maker takes an action. Our main result is that, in contrast to a static environment, full information revelation is possible. The gradual revelation of information and the eventual full revelation is supported by the dynamic rewards and punishments. The construction of a fully revealing equilibrium relies on two key features. The first feature is that the expert is incentivized, via appropriate actions, to join separable groups in which she initially pools with far-away types, then later reveals …

A Practical Asymptotic Variance Estimator For Two-Step Semiparametric Estimators, Daniel Ackerberg, Xiaohong Chen, Jinyong Hahn

Cowles Foundation Discussion Papers

The goal of this paper is to develop techniques to simplify semiparametric inference. We do this by deriving a number of numerical equivalence results. These illustrate that in many cases, one can obtain estimates of semiparametric variances using standard formulas derived in the already-well-known parametric literature. This means that for computational purposes, an empirical researcher can ignore the semiparametric nature of the problem and do all calculations “as if” it were a parametric situation. We hope that this simplicity will promote the use of semiparametric procedures.

Vertical Linkages And The Collapse Of Global Trade, Rudolfs Bems, Robert C. Johnson, Kei-Mu Yi

Dartmouth Scholarship

A common view is that cross-border vertical linkages played a key role in the 2008-2009 collapse of global trade. This paper presents two accounting results from a global input-output framework that shed light on this channel. We feed in observed changes in final demand and find that trade in final goods fell by twice as much as trade in intermediate goods. Nevertheless, intermediate goods account for more than two-fifths of the trade collapse. We also find that vertical specialization trade fell 13 percent, while value-added trade fell by 10 percent, because declines in demand were largest in highly vertically-specialized sectors.

The Residual Income Approach To Housing Affordability: The Theory And The Practice, Michael E. Stone, Terry Burke, Liss Ralston

Community Studies Faculty Publication Series

The residual income approach to housing affordability is one that looks at what different household types can afford to spend on housing after taking into account the other necessary expenditures of living. It is an alternative to benchmark measures of affordability as used in social housing rent setting in Australia (the 25% rule) or assessing the overall affordability in the wider housing market (the 30/40 rule) as commonly used by a range of housing affordability researchers in Australia.

This Positioning Paper does two things. Part A provides an overview, using existing literature, of the various semantic, substantive and definitional issues …

Authentic Leadership In Sports Teams, Greg Houchin

Masters Theses and Doctoral Dissertations

Authentic leadership includes a positive moral perspective characterized by high ethical standards that guide decision making and behavior. The measurement of authentic leadership is aimed at a leader’s ability to be genuine. This study identified and analyzed authentic leaders on sports teams. Group cohesion was also assessed. The purpose was to determine whether authentic leadership would lead to performance when mediated by team cohesion and trust. Survey analyses were used to assess several teams. Results indicated that sports teams may benefit from training in authentic leadership. Authentic leadership predicts higher levels of trust, team cohesion, and group performance.

Factors Contributing To Young Worker Atod Use Both And Off The Job, Sara Michelle Martin

Masters Theses and Doctoral Dissertations

The present study was designed to evaluate whether workplace factors such as permissive culture or workplace stress are associated with the day-to-day use of alcohol, tobacco or other drugs (ATOD) among young adult workers (N = 187). Previous research has found stronger relationships between ATOD use and workplace factors when ATOD use was measured on and off the job separately. To isolate on the job factors from off the job ATOD use, participants were asked to complete daily diary entries regarding their workday. It was predicted that workers who report stressful workdays and ATOD-tolerant workplace cultures will report more ATOD …

A Test That Combines Frequency And Quantitative Information, Norman Cliff

Journal of Modern Applied Statistical Methods

In many simple designs, observed frequencies in subclasses defined by a qualitative variable are compared to the frequencies expected on the basis of population proportions, design parameters or models. Often there is a quantitative variable which may be affected in the same way as the frequencies. Its differences among the groups may also be analyzed. A simple test is described that combines the effects on the frequencies and on the quantitative variable based on comparing the sums of the values for the quantitative value within each group to the random expectation. The sampling variance of the difference is derived and …

Comparing The Strength Of Association Of Two Predictors Via Smoothers Or Robust Regression Estimators, Rand R. Wilcox

Journal of Modern Applied Statistical Methods

Consider three random variables, Y , X₁ and X₂, having some unknown trivariate distribution and let n²_j (j = 1, 2) be some measure of the strength of association between Y and X_j. When n²_j is taken to be Pearson’s correlation numerous methods for testing H_o : n²₁ = n²₂ have been proposed. However, Pearson’s correlation is not robust and the methods for testing H₀ are not level robust in general. This article examines methods for testing H₀ based on a robust fit. The …

Bias In Monte Carlo Simulations Due To Pseudo-Random Number Generator Initial Seed Selection, Jack C. Hill, Shlomo S. Sawilowsky

Journal of Modern Applied Statistical Methods

Pseudo-random number generators can bias Monte Carlo simulations of the standard normal probability distribution function with initial seeds selection. Five generator designs were initial-seeded with values from 10000_HEX to 1FFFF_HEX, estimates of the mean were calculated for each seed, the distribution of mean estimates was determined for each generator and simulation histories were graphed for selected seeds.

New Perspectives In Applying The Regression-Discontinuity Design For Program Evaluation: A Simulation Analysis, Sally A. Lesik

Journal of Modern Applied Statistical Methods

Evaluating educational programs is a core component of assessment. One challenge occurs because participants often enter into programs with diverse skills and backgrounds. The regression-discontinuity design has been used to evaluate programs amongst a diverse group, but noncompliance is a limitation. A simulation analysis illustrates the impact of noncompliance.

General Piecewise Growth Mixture Model: Word Recognition Development For Different Learners In Different Phases, Amery D. Wu, Bruno D. Zumbo, Linda S. Siegel

Journal of Modern Applied Statistical Methods

The General Piecewise Growth Mixture Model (GPGMM), without losing generality to other fields of study, can answer six crucial research questions regarding children’s word recognition development. Using child word recognition data as an example, this study demonstrates the flexibility and versatility of the GPGMM in investigating growth trajectories that are potentially phasic and heterogeneous. The strengths and limitations of the GPGMM and lessons learned from this hands-on experience are discussed.

A Simulation Study Of The Relative Efficiency Of The Minimized Integrated Square Error Estimator (L2e) For Phase I Control Charting, John N. Dyer

Journal of Modern Applied Statistical Methods

Parameter estimates used in control charting, the sample mean and variance, are based on maximum likelihood estimation (MLE). Unfortunately, MLEs are not robust to contaminated data and can lead to improper conclusions regarding parameter values. This article proposes a more robust estimation technique; the minimized integrated square error estimator (L2E).

Maximum Likelihood Solution For The Linear Structural Relationship With Three Parameters Known, Androulla Michaeloudis

Journal of Modern Applied Statistical Methods

A maximum likelihood solution is obtained for the simple linear structural relation model where the underlying incidental distribution and one error variance are assumed known. Expressions for the asymptotic standard errors of the maximum likelihood estimates are obtained and these are verified using a simulation study.

Logistic Regression Models For Higher Order Transition Probabilities Of Markov Chain For Analyzing The Occurrences Of Daily Rainfall Data, Narayan Chanra Sinha, M. Ataharul Islam, Kazi Saleh Ahamed

Journal of Modern Applied Statistical Methods

Logistic regression models for transition probabilities of higher order Markov models are developed for the sequence of chain dependent repeated observations. To identify the significance of these models and their parameters a test procedure for a likelihood ratio criterion is developed. A method of model selection is suggested on the basis of AIC and BIC procedures. The proposed models and test procedures are applied to analyze the occurrences of daily rainfall data for selected stations in Bangladesh. Based on results from these models, the transition probabilities of first order Markov model for temperature and humidity provided the most suitable option …

Roadmap To Success: Scholarly Communications At Wayne State University, Suzan A. Alteri, Jonathan Mcglone

Library Scholarly Publications

Despite the role of libraries in the open access movement, many librarians still need education on differing viewpoints, the vocabulary, and initiatives surrounding the movement. Recently, Wayne State University Librarians formed a Scholarly Communications team to introduce open access and scholarly communication reform. This team took a leadership role in educating liaison librarians, providing campus-wide workshops on research dissemination, and creating special open access week programming. How this was accomplished, the positive outcomes and future opportunities generated by these collective efforts will be discussed.

World-Class Universities Or World-Class Systems? Rankings And Higher Education Policy Choices, Ellen Hazelkorn

Other resources

Is it always a good thing when a university rises up the rankings and breaks into the top 100? Do rankings raise standards by encouraging competition or do they undermine the broader mission to provide education? Should rankings be used to help decide educational policy and the allocation of scare financial resources? Should policy aim to develop world-class universities or to make the system world-class?

University rankings have dominated headlines and the attention of political and university leaders wherever or whenever they are published or mentioned. Politicians regularly refer to them as a measure of their nation’s economic strengths and …

How Vision Problems Affect Our Lives

Nicole Horn

Faculty Sponsor: Charles Collyer, Psychology

Vision is much more than simply being able to see 20/20. There are a number of different visual problems which can impact how we see and interact with the world around us. One visual skill, which is looked at in this research, is convergence. Convergence is the ability to turn the eyes so that they both focus in on the same object, at the same time, and at the same distance in space.  If the eyes either underconverge or overconverge, this can lead to an altered perception …

Development For The Past, Present, And Future: Defining And Measuring Sustainable Development, Max Cantor

Senior Honors Projects

In 1987, the United Nations released the Brundtland Report, which defined sustainable development as “development which meets the needs of the present without compromising the ability of future generations to meet their own needs.” While this definition provides a relatively stable theoretical base from which development economists and political scientists can begin to tackle issues surrounding sustainable development, the inherently amorphous nature of this definition has also created a fair amount of ambiguity in both the economic literature surrounding sustainable development and the subsequent attempts by economists to measure it.

Historically, those interested in the science of development have typically …
