Applied statistics practice problems
Introduction. This book contains a collection of problems, and my solutions to them, in applied statistics with R. These come from my courses STAC32, STAC33, and STAD29 at the University of Toronto Scarborough. The problems were originally written in Sweave (that is, LaTeX with R code chunks), using the exam document class, using data sets stolen from numerous places (textbooks, websites etc).The edX course focuses on animations, interactive features, readings, and problem-solving, and is complementary to the Stat 110 lecture videos on YouTube, which are available at https://goo.gl/i7njSb. The Stat110x animations are available within the course and at https://goo.gl/g7pqTo
