• ### Chapter 084. Head and Neck Cancer (Part 6)

Chemoprevention β-Carotene and cis-retinoic acid can lead to the regression of leukoplakia. However, cis-retinoic acid does not reduce the incidence of second primaries Treatment Complications Complications from treatment of head and neck cancer are usually correlated to the extent of surgery and exposure of normal tissue structures to radiation. Currently, the extent of surgery has been limited or completely replaced by chemotherapy and radiation therapy as the primary approach. Acute complications of radiation include mucositis and dysphagia.

• ### Reading Statistics and Research

In the first edition of this book, I claimed that humanity could be divided into three groups: (1) those who conduct their own research studies, (2) those who do not formally engage in the research process but nonetheless encounter the results of others’ investigations, and (3) those who are neither “makers” nor “consumers” of research claims. Now, nearly 40 years since I made that statement, I still believe that every person on the face of the Earth can be classified into one of those three groups.

• ### Exposures to fine particulate air pollution and respiratory outcomes in adults using two national datasets: a cross-sectional study

The French work was based on the available Black Smoke (BS) data. A correlation analysis between BS and PM10 (TEOM method7 ) was first carried out. It was found that at urban background sites, BS and PM10 (TEOM) are about equal. Following this, linear relationships were sought between the BS data and land use categories in the areas surrounding the measurement sites. Multiple regression analysis was performed for three categories of sites: urban, suburban and rural. Based on these regressions and using the land use data set, a PM10 map was established.

• ### External Debt and Economic Growth Relationship Using the Simultaneous Equations

The analysis is limited to the post-World War II period. Using this period provides an adequate sample for the multivariate regression analysis that is used to examine correlation. The top statutory tax rates are examined because the current Congressional debate over the fate of the 2001 and 2003 Bush-era tax cuts focuses on the statutory tax rates affecting the highest income taxpayers. For an overview of the broader issues of these relationships see CRS Report R42111, Tax Rates and Economic Growth, by Jane G. Gravelle and Donald J. Marples. ...

• ### Báo cáo khoa học: "A Re-examination on Features in Regression Based Approach to Automatic MT Evaluation"

Machine learning methods have been extensively employed in developing MT evaluation metrics and several studies show that it can help to achieve a better correlation with human assessments. Adopting the regression SVM framework, this paper discusses the linguistic motivated feature formulation strategy. We argue that “blind” combination of available features does not yield a general metrics with high correlation rate with human assessments.

• ### Báo cáo khoa học: "Regression for Sentence-Level MT Evaluation with Pseudo References"

Many automatic evaluation metrics for machine translation (MT) rely on making comparisons to human translations, a resource that may not always be available. We present a method for developing sentence-level MT evaluation metrics that do not directly rely on human reference translations. Our metrics are developed using regression learning and are based on a set of weaker indicators of ﬂuency and adequacy (pseudo references). Experimental results suggest that they rival standard reference-based metrics in terms of correlations with human judgments on new test instances. ...

• ### Research " Essays in Macroeconomics and the Economics of Higher Education "

Essays in Macroeconomics and the Economics of Higher Education In single-MSA regressions of test scores on student characteristics, the above arguments imply greater attenuation of the peer group coefficient in MSAs with less stratified schools. As choice is positively correlated with stratification, this produces a tendency toward larger estimated coefficients (i.e. less bias toward zero) in high-choice MSAs.

• ### Research " Migration and Economic Development: The Case of the Mouride Brotherhood From Senegal to the Washington D.C. Metropolitan Area, 1990-2000 "

Migration and Economic Development: The Case of the Mouride Brotherhood From Senegal to the Washington D.C. Metropolitan Area, 1990-2000 Effectiveness sorting should be observable as a magnification of the causal peer effect, as it creates a positive correlation between the peer group and an omitted variable school effectivenessin regression models for student outcomes.

• ### Applied Multiple Regression

This book had its origin over 30 years ago, when it became apparent to Jack Cohen that there were relationships between multiple regression and correlation (MRC) on the one hand and the analysis of variance (ANOVA) on the other which were undreamed of (or at least did not appear) in the standard textbooks with which he was familiar. On the contrary, the texts of the era treated MRC and ANOVA as wholly distinct systems of data analysis intended for types of research that differed fundamentally in design, goals, and types of variables.

• ### Expert Guide Investment Funds

In particular, note that there are two potential sources of timing-related fund returns that are correlated with public information. The ﬁrst, predictable fund risk-loadings, may be due to changing stock-level risk loadings, to ﬂows into the funds, or to manager timing of the benchmarks. The second exploits predictability in the benchmark returns themselves. Such predictability is captured through the time-series regression in Eq. (2). Because both of these timing components are assumed to be easily replicated by an investor, we do not consider them to be based on manager ‘‘skill.
