The 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).

An early definition of mathematics in terms of logic was Benjamin Peirce's "the science that draws necessary conclusions" (1870).[24] In the Principia Mathematica, Bertrand Russell and Alfred North Whitehead advanced the philosophical program known as logicism, and attempted to prove that all mathematical concepts, statements, and principles can be defined and proven entirely in terms of symbolic logic. A logicist definition of mathematics is Russell's "All Mathematics is Symbolic Logic" (1903)

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.

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.

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.

Despite the gradual shift towards a market economy that commenced in 1986, and in spite of the emphasis on state owned enterprise (SOE) reform and privatization in the structural adjustment programs formulated since the mid1990s, the state sector continues to play a leading role in the Vietnamese economy. The dominant position of the state sector is confirmed in official statistics and a variety of studies on the Vietnamese economy.

This book is intended for a rigorous introductory Ph.D. level course in econometrics, or for use in a field course in econometric theory. It is based on lecture notes that I have developed during the period 19972003 for the first semester econometrics course “Introduction to Econometrics” in the core of the Ph.D. program in economics at the Pennsylvania State University. Initially these lecture notes were written as a companion to Gallant’s (1997) textbook, but have been developed gradually into an alternative textbook.

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 is the first of two reports that address the complex issue of incorporating the needs of climate research into the National Polarorbiting Operational Environmental Satellite System (NPOESS). NPOESS, which has been driven by the imperative of reliably providing shortterm weather information, is itself a union of heretofore separate civilian and military programs. It is a marriage of convenience to eliminate needless duplication and reduce cost, one that appears to be working.

Before starting with the process of acquiring, correcting and measuring images, it seems important to spend a chapter addressing the important question of just what it is that can and should be measured, and what cannot or should not be. The temptation to just measure everything that software can report, and hope that a good statistics program can extract some meaningful parameters, is both naïve and dangerous. No statistics program can correct, for instance, for the unknown but potentially large bias that results from an inappropriate sampling procedure.

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.
