Statistical programming

This book is about data analysis and the programming language called R. This is rapidly becoming the de facto standard among professionals, and is used in every conceivable discipline from science and medicine to business and engineering. R is more than just a computer program; it is a statistical programming environment and language. R is free and open source and is therefore available to everyone with a computer. It is very powerful and flexible, but it is also unlike most of the computer programs you are likely used to.

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 (NSCG).

INTENDED FOR CLASS USE OR SELFSTUDY, this text aspires to introduce statistical methodology to a wide audience, simply and intuitively, through resampling from the data at hand. The resampling methods—permutations and the bootstrap—are easy to learn and easy to apply. They require no mathematics beyond introductory highschool algebra, yet are applicable in an exceptionally broad range of subject areas.

We introduce a novel search algorithm for statistical machine translation based on dynamic programming (DP). During the search process two statistical knowledge sources are combined: a translation model and a bigram language model. This search algorithm expands hypotheses along the positions of the target string while guaranteeing progressive coverage of the words in the source string. We present experimental results on the Verbmobil task.

This volume describes the essential tools and techniques of statistical signal processing. At every stage, theoretical ideas are linked to specific applications in communications and signal processing. The book begins with an overview of basic probability, random objects, expectation, and secondorder moment theory, followed by a wide variety of examples of the most popular random process models and their basic uses and properties.

I am grateful for the contributions that many people have made to this book. Ed Maggin was the first to teach me Statistical Thermodynamics and his class notes were always a point of reference. The late Ted H. Davis gave me encouragement and invaluable feedback. Dan Bolintineanu and Thomas Jikku read the final draft and helped me make many corrections. Many thanks go to the students who attended my course in Statistical Thermodynamics and who provided me with many valuable comments regarding the structure of the book.

Learn to program a computer without the jargon and complexity of many programming books. Suitable for anybody age 10 to 100+ who wants to learn and is ready to experiment. This book engages through media (sound, color, shapes, and text to speech) and then introduces the concepts of structured programming (loops, conditions, variables...), using BASIC256. You will learn to program as you make animations, games, and fun applications. Full source code to example programs are given to start experimentation and self exploration....

Researchers in both machine Iranslation (e.g., Brown et al., 1990) and bilingual lexicography (e.g., Klavans and Tzoukermann, 1990) have recently become interested in studying parallel texts, texts such as the Canadian Hansards (parliamentary proceedings) which are available in multiple languages (French and English). This paper describes a method for aligning sentences in these parallel texts, based on a simple statistical model of character lengths. The method was developed and tested on a small trilingual sample of Swiss economic reports.

In this paper, we describe a Dynamic Programming (DP) based search algorithm for statistical translation and present experimental results. The statistical translation uses two sources of information: a translation model and a language model. The language model used is a standard bigram model. For the translation lnodel, the alignment probabilities are made dependent on the differences in the alignment positions rather than on the absolute positions.

We present the ﬁrst version of a new declarative programming language. Dyna has many uses but was designed especially for rapid development of new statistical NLP systems. A Dyna program is a small set of equations, resembling Prolog inference rules, that specify the abstract structure of a dynamic programming algorithm. It compiles into efﬁcient, portable, C++ classes that can be easily invoked from a larger application.

Stochastic uniﬁcationbased grammars (SUBGs) deﬁne exponential distributions over the parses generated by a uniﬁcationbased grammar (UBG). Existing algorithms for parsing and estimation require the enumeration of all of the parses of a string in order to determine the most likely one, or in order to calculate the statistics needed to estimate a grammar from a training corpus.

Managers always want to do something to improve how their organizations function. The combined effects of global competition, the growth in business books and magazines, and business consultancy has led to a neverending se ries of fads to fix organizations. It often seems that these do more to confuse than inform people, leading to one change program after another, what the peo ple at HarleyDavidson dubbed many years ago, “AFP,” Another Fine Program (often translated differently internally). ...
