Computer software is an essential tool for many statisticalmodelling and data analysis techniques, aiding in the implementation oflarge data sets in order to obtain useful results. R is one of the mostpowerful and flexible statistical software packages available, andenables the user to apply a wide variety of statistical methods rangingfrom simple regression to generalized linear modelling. Statistics: AnIntroduction using R is a clear and concise introductory textbook tostatistical analysis using this powerful and free software, and followson from the success of the author's previous best-selling titleStatistical Computing.
* Features step-by-step instructions that assume no mathematics,statistics or programming background, helping the non-statistician tofully understand the methodology.
* Uses a series of realistic examples, developing step-wise fromthe simplest cases, with the emphasis on checking the assumptions (e.g.constancy of variance and normality of errors) and the adequacy of themodel chosen to fit the data.
* The emphasis throughout is on estimation of effect sizes andconfidence intervals, rather than on hypothesis testing.
* Covers the full range of statistical techniques likely to beneed to analyse the data from research projects, including elementarymaterial like t-tests and chi-squared tests, intermediate methods likeregression and analysis of variance, and more advanced techniques likegeneralized linear modelling.
* Includes numerous worked examples and exercises within each chapter.
Statistics: An Introduction using R is the first text to offersuch a concise introduction to a broad array of statistical methods, ata level that is elementary enough to appeal to a broad range ofdisciplines. It is primarily aimed at undergraduate students inmedicine, engineering, economics and biology - but will also appeal topostgraduates who have not previously covered this area, or wish toswitch to using R.
