The U.S. National Science Foundation (NSF) has long collected
information on the number and characteristics of individuals with
education or employment in science and engineering and related
fields in the United States. One of the three vehicles employed by NSF for
collecting this information is the National Survey of College Graduates
Data Analysis and Presentation Skills: An Introduction for the Life and Medical Sciences is an invaluable text allowing students to develop appropriate key skills when designing experiments, generating results, analysing data and ultimately presenting findings to academics and referees. Taking a hands-on approach, each of these key areas is introduced clearly and carefully, showing how to access and evaluate information using a variety of resources.
Basic analytical theory is gradually introduced alongside practical applications to enhance student understanding.
Statistical methods for survival data analysis have continued to flourish in the
last two decades. Applications of the methods have been widened from their
historical use in cancer and reliability research to business, criminology,
epidemiology, and social and behavioral sciences. The third edition of Statistical
Methods for Survival Data Analysis is intended to provide a comprehensive
introduction of the most commonly used methods for analyzing survival data.
It begins with basic definitions and interpretations of survival functions....
This book is designed to give you the essential, nitty-gritty
information typically covered in a first semester statistics
course. It’s bottom-line information for you to use as a
refresher, a resource, a quick reference, and/or a study guide.
It helps you decipher and make important decisions about
statistical polls, experiments, reports and headlines with confidence,
being ever aware of the ways people can mislead you
with statistics, and how to handle it.
Non-market valuation has become a broadly accepted and widely practiced means of measuring the economic values of the environment and natural resources. In this book, the authors provide a guide to the statistical and econometric practices that economists employ in estimating non-market values. The authors develop the econometric models that underlie the basic methods: contingent valuation, travel cost models, random utility models and hedonic models.
This book challenges the conventional wisdom that natural resource wealth promotes autocracy. Oil and other forms of mineral wealth can promote both authoritarianism and democracy, the book argues, but they do so through different mechanisms; an understanding of these different mechanisms can help elucidate when either the authoritarian or democratic effects of resource wealth will be relatively strong.
Ebook Statistics with Stata is the latest edition in Professor Lawrence C. Hamilton’s popular Statistics with Stata series. Intended to bridge the gap between statistical texts and Stata’s own documentation, Statistics with Stata demonstrates how to use Stata to perform a variety of tasks.
Paraphrase generation (PG) is important in plenty of NLP applications. However, the research of PG is far from enough. In this paper, we propose a novel method for statistical paraphrase generation (SPG), which can (1) achieve various applications based on a uniform statistical model, and (2) naturally combine multiple resources to enhance the PG performance. In our experiments, we use the proposed method to generate paraphrases for three different applications.
We present several unsupervised statistical models for the prepositional phrase attachment task that approach the accuracy of the best supervised methods for this task. Our unsupervised approach uses a heuristic based on attachment proximity and trains from raw text that is annotated with only part-of-speech tags and morphological base forms, as opposed to attachment information. It is therefore less resource-intensive and more portable than previous corpus-based algorithm proposed for this task. ...
We explore how to improve machine translation systems by adding more translation data in situations where we already have substantial resources. The main challenge is how to buck the trend of diminishing returns that is commonly encountered. We present an active learning-style data solicitation algorithm to meet this challenge. We test it, gathering annotations via Amazon Mechanical Turk, and ﬁnd that we get an order of magnitude increase in performance rates of improvement.
Monolingual translation probabilities have recently been introduced in retrieval models to solve the lexical gap problem. They can be obtained by training statistical translation models on parallel monolingual corpora, such as question-answer pairs, where answers act as the “source” language and questions as the “target” language. In this paper, we propose to use as a parallel training dataset the deﬁnitions and glosses provided for the same term by different lexical semantic resources.
This paper proposes a novel method that exploits multiple resources to improve statistical machine translation (SMT) based paraphrasing. In detail, a phrasal paraphrase table and a feature function are derived from each resource, which are then combined in a log-linear SMT model for sentence-level paraphrase generation. Experimental results show that the SMT-based paraphrasing model can be enhanced using multiple resources. The phrase-level and sentence-level precision of the generated paraphrases are above 60% and 55%, respectively.
We present a Czech-English statistical machine translation system which performs tree-to-tree translation of dependency structures. The only bilingual resource required is a sentence-aligned parallel corpus. All other resources are monolingual. We also refer to an evaluation method and plan to compare our system’s output with a benchmark system.
Operations and industrial modeling and management have a long history
dating back to the first Industrial Revolution. Scheduling, inventory control,
production planning, projects management, control charts, statistical
records, customer satisfaction questionnaires, rankings and benchmarking.
are some of the tools used for the purpose of better managing operations
Introduction to Quantitative Research Methods is a student-friendly introduction to quantitative research methods and basic statistics. It uses a detective theme throughout the text and in multimedia courseware to show how quantitative methods have been used to solve real-life problems. The book focuses on principles and techniques that are appropriate to introductory level courses in media, psychology and sociology. Examples and illustrations are drawn from historical and contemporary research in the social sciences. ...
The latest edition of International Economics improves and builds upon the popular
features of previous editions. The graphs, tables and statistics are of course all updated, but
also added are improved sections on topics including:
• new developments in international trade agreements and the latest round of
international trade talks
• international financial crisis
• a new section on current controversies in the international monetary system
This book is intended to serve as the textbook for a rst-year graduate course in econometrics.
It can be used as a stand-alone text, or be used as a supplement to another text.
Students are assumed to have an understanding of multivariate calculus, probability theory,
linear algebra, and mathematical statistics. A prior course in undergraduate econometrics would
be helpful, but not required.
For reference, some of the basic tools of matrix algebra, probability, and statistics are reviewed
in the Appendix....
This third edition of Analytical Chemistry for Technicians is the culmination and ﬁnal product of a series
of four projects funded by the National Science Foundation’s Advanced Technological Education Program
and two supporting grants from the DuPont Company. The grant funds have enabled me to utilize an
almost limitless reservoir of human and other resources in the development and completion of this
manuscript and to vastly improve and update the previous edition. A visible example is the CD that
accompanies this book.
Perhaps the most difficult method of the four methods, memorizing is the technique many novice speakers start off with, because they are under the impression that this is how all speeches are prepared and delivered
The most polished speakers forget their words halfway through
