Statistical methods are a key part of data science, yet few data scientists have formal statistical training. Courses and books on basic statistics rarely cover the topic from a data science perspective. The second edition of this popular guide adds comprehensive examples in Python, provides practical guidance on applying statistical methods to data science, tells you how to avoid their misuse, and gives you advice on what’s important and what’s not. Many data science resources incorporate statistical methods but lack a deeper statistical perspective. If you’re familiar with the R or Python programming languages and have some exposure to statistics, this quick reference bridges the gap in an accessible, readable format. With this book, you’ll learn: Why exploratory data analysis is a key preliminary step in data science How random sampling can reduce bias and yield a higher-quality dataset, even with big data How the principles of experimental design yield definitive answers to questions How to use regression to estimate outcomes and detect anomalies Key classification techniques for predicting which categories a record belongs to Statistical machine learning methods that "learn" from data Unsupervised learning methods for extracting meaning from unlabeled data

Conceived in 1976 and published in 1980, LEGEND exemplifies the political and linguistic commitments of then-nascent Language writing. Coauthored by Bruce Andrews, Charles Bernstein, Ray DiPalma, Steve McCaffery, and Ron Silliman, the work was composed on typewriters and developed through the mail. The twenty-six poems of the volume bring together every possible permutation of collaborative authorship in one-, two-, three-, and five-author combinations, revealing the evolution of distinctive styles against and in conversation with others. Along with a complete reproduction of the original text, LEGEND: The Complete Facsimile in Context includes a critical introduction by editors Matthew Hofer and Michael Golston, a generous selection of material from the authors' correspondence, and a new collaborative piece by the authors. This book will be an essential resource to students and scholars in twentieth-century poetry and poetics.

In this selection of shorter lyric poems, celebrated Language poet Bruce Andrews offers his charismatic blend of satire, wit and jouissance, creating a dizzying picture of modern America. In these poems Andrews explores a more intimate and domestic register, further reminding us of the astonishing range of this contemporary master.

"Ok murky in alter all end, unpredictable day, with rainshine any degree night, the sun kin warm and hot. Enough stone or other jugs lineup of whatever is In Through Out That's light as much as known Differences evanesce Like, where and/or what on the equator might be french or spanish Longitude and latitude, yep yep sure Americana."--Larry Eigner, commentary on a selection from Ger-trude Stein's "Tender Buttons"
This selection of essays and poetry from the first three volumes of L=A=N=G=U=A=G=E magazine dis-cusses a "spectrum of writing that places its attention primarily on language and ways of making meaning, that takes for granted neither vocabulary, grammar, process, shape, syntax, program, nor sub-ject matter." (Bernstein and Andrews) The various writers shun labels, slogans, or catch-phrases; their exploration of the ways that meanings and values are re-vealed through the written word is in-tended to open the field of poetic activity, not close it.
The common thread of these essays is the multitude and scope of words' refer-ential powers--denotative, connotative, and associational; and studying these powers is ultimately a social and political activity as well as an aesthetic one.
