Statistics books for (free) download | R-statistics blogThe second volume, by Michael Crawley, is an R code sequel to his monumental Statistical Computing reviewed in Clin Chem ;—62 , which comprehensively explained statistical procedures using the S-Plus language which is closely related to R. The truth is that there is no substitute for experience; the way to know what to do, is to have done it properly lots of times before. Is the response variable continuous, a count, a proportion, a time-at-death, or a category? Is the explanatory variable continuous or variable, or a mixture of both? Once these aspects are established, the appropriate statistical method will suggest itself—ANOVA, ANCOVA, normal regression, logistic regression, log-linear models, binary logistic analysis, and survival analysis. Having laid out the statistical roadmap, the next few chapters cover the essential statistical tools: dataframes, central tendency, variance this topic, Crawley suggests, is the most important one in the book because of its central importance in statistical analysis , the statistics of single and double samples.
