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 scienceHow random sampling can reduce bias and yield a higher-quality dataset, even with big dataHow the principles of experimental design yield definitive answers to questionsHow to use regression to estimate outcomes and detect anomaliesKey classification techniques for predicting which categories a record belongs toStatistical machine learning methods that "learn" from dataUnsupervised learning methods for extracting meaning from unlabeled data

For over 50 years Heavy Weather Sailing has been regarded as the ultimate international authority on surviving storms at sea aboard sailing and motor vessels.In this book, former Commodore of the Ocean Cruising Club Martin Thomas brings together a wealth of expert advice from many of the great sailors of the present, including fresh accounts of yachts overtaken by extreme weather, from Ewan Southby-Tailyour, Alex Whitworth and Dag Pike to Larry and Lin Pardey, Matt Sheahan and Andrew Claughton.The expert advice section has been updated in line with current thinking, with major new additions tackling preventing or coping with lightning strikes, navigating in heavy weather with both paper and electronic charts, the choice and use of tenders in severe weather, and special problems faced by the new generation of foiled cruising boats. For the first time the book also covers the unique challenges presented by weather in high latitudes, with more yachts crossing the Drake Passage and attempting the North West Passage. These revisions ensure that Heavy Weather Sailing is as relevant, useful and instructive for today’s sailor venturing offshore as it ever was.This is the definitive book for crews of any size contemplating voyages out of sight of land anywhere in the world, whether racing or cruising. It gives a clear message regarding the preparations required, and the tactics to consider when it comes on to blow.

Wie kann man orkanartige Sturme auf See sicher uberstehen? Welche Taktiken halten das Boot bei schwerem Wetter manovrierfahig, und wie sollte eine Yacht konstruiert und ausgerustet sein, um Kentern vorzubeugen? Diese und viele weitere Fragen behandelt das bewahrte Standardwerk "e;Schwerwettersegeln"e;, das umfassend uberarbeitet und erweitert wurde. Theorie und Praxis des SchwerwettersegelnsDer erste Teil des Buches widmet sich der Theorie der Bootskonstruktionen und -ausrustungen. Es beleuchtet das Verhalten von Segel- und Motoryachten, Einrumpf- und Mehrrumpfbooten sowie Festrumpfschlauchbooten unter extremen Wetterbedingungen und stellt die geeigneten Schwerwettertaktiken vor. Die Eignung von Ausrustungen wie Masten, Trysegeln, See- und Treibankern wird eingehend besprochen, und die neuesten Erkenntnisse und Entwicklungen werden vorgestellt. Im praktischen Teil bietet das Buch wertvolle Methoden und Tipps zum sicheren Abwettern starker und orkanartiger Sturme. Durch die Analyse konkreter Berichte zu Schwerwettereignissen vermittelt der Autor praxisnahe Ratschlage fur jeden Segler. Umfassende Theoriekapitel: Erklart das Verhalten verschiedener Bootstypen und stellt passende technische Ausrustungen fur schweres Wetter vor. Praktische Handlungsempfehlungen: Bietet Strategien und Tipps basierend auf realen Schwerwettererfahrungen und Regattaerfolgen.

Los métodos estadísticos son una parte fundamental de la ciencia de datos, pero pocos científicos de datos tienen una formación avanzada en estadística. Los cursos y libros sobre estadística básica rara vez tratan el tema desde la perspectiva de la ciencia de datos. La segunda edición de este libro incluye ejemplos detallados de Python, ofrece una orientación práctica sobre la aplicación de los métodos estadísticos a la ciencia de datos, te indica cómo evitar su uso incorrecto y te aconseja sobre lo que es y lo que no es importante.Muchos recursos de la ciencia de datos incorporan métodos estadísticos, pero carecen de una perspectiva estadística más profunda. Si estás familiarizado con los lenguajes de programación R o Python y tienes algún conocimiento de estadística, este libro suple esas carencias de una forma práctica, accesible y clara.Con este libro aprenderás:Por qué el análisis exploratorio de datos es un paso preliminar clave en la ciencia de datosCómo el muestreo aleatorio puede reducir el sesgo y ofrecer un conjunto de datos de mayor calidad, incluso con Big DataCómo los principios del diseño experimental ofrecen respuestas definitivas a preguntasCómo utilizar la regresión para estimar resultados y detectar anomalíasTécnicas de clasificación esenciales para predecir a qué categorías pertenece un registroMétodos estadísticos de aprendizaje automático que "aprenden" a partir de los datosMétodos de aprendizaje no supervisados para extraer significado de datos sin etiquetarPeter Bruce es el fundador del Institute for Statistics Education en Statistics.com.Andrew Bruce es científico investigador jefe en Amazon y tiene más de 30 años de experiencia en estadística y ciencia de datos.Peter Gedeck es científico de datos senior en Collaborative Drug Discovery, desarrolla algoritmos de aprendizaje automático para pronosticar propiedades de posibles futuros fármacos.
