Bootstrapping is a conceptually simple statistical technique to increase the quality of estimates, conduct robustness checks and compute standard errors for virtually any statistic. This book provides an intelligible and compact introduction for students, scientists and practitioners. It not only gives a clear explanation of the underlying concepts but also demonstrates the application of bootstrapping using Python and Stata.

Wer die Grundlagen von Python beherrscht und jetzt tiefer einsteigen m chte, kommt in diesem Buch auf seine Kosten. Mittels konkreter Anwendungsbeispiele aus verschiedenen Fachgebieten wird aufgezeigt, wie man Python produktiv zur Probleml sung einsetzen kann. Diskutiert werden dabei neben den allgemeinen L sungsideen auch die Spezifika von Python und wie diese gewinnbringend genutzt werden k nnen. Somit veranschaulicht das Buch allgemeine Konzepte der Programmierung, wie beispielsweise Algorithmen, Rekursion und Datenstrukturen, und lehrt problemorientiertes Denken.

Stata is one of the most popular statistical software in the world and suited for all kinds of users, from absolute beginners to experienced veterans. This book offers a clear and concise introduction to the usage and the workflow of Stata. Included topics are importing and managing datasets, cleaning and preparing data, creating and manipulating variables, producing descriptive statistics and meaningful graphs as well as central quantitative methods, like linear (OLS) and binary logistic regressions and matching. Additional information about diagnostical tests ensures that these methods yield valid and correct results that live up to academic standards. Furthermore, users are instructed how to export results that can be directly used in popular software like Microsoft Word for seminar papers and publications. Lastly, the book offers a short yet focussed introduction to scientific writing, which should guide readers through the process of writing a first quantitative seminar paper or research report. The book underlines correct usage of the software and a productive workflow which also introduces aspects like replicability and general standards for academic writing. While absolute beginners will enjoy the easy to follow point-and-click interface, more experienced users will benefit from the information about do-files and syntax which makes Stata so popular. Lastly, a wide range of user-contributed software („Ados") is introduced which further improves the general workflow and guarantees the availability of state of the art statistical methods.
