📮 Power and Sample Size in R by Catherine M. Crespi (.ePUB)+

Power and Sample Size in R guides the reader through power and sample size calculations for a wide variety of study outcomes and designs and illustrates their implementation in R software. It is designed to be used as a learning tool for students as well as a resource for experienced statisticians and investigators. The book begins by explaining the process of power calculation step by step at an introductory level and then builds to increasingly complex and varied topics. For each type of study design, the information needed to perform a calculation and the factors that affect power are explained. Concepts are explained with statistical rigor but made accessible through intuition and examples. The book demonstrates calculations in R using examples. Only a basic proficiency in R is assumed. We use functions from the powertools package, which was developed as a companion R package to this book, as well as other packages. There are many packages for various types of power and sample size calculations available in R, and we try to summarize available resources in each chapter. The index includes not only concepts and topics but also the R functions and packages mentioned in the book.
