Statistical Computation for Programmers, Scientists, Quants, Excel Users, and Other Professionals
Using the open source R language, you can build powerful statistical models to answer many of your most challenging questions. R has traditionally been difficult for non-statisticians to learn, and most R books assume far too much knowledge to be of help. R for Everyone, Second Edition, is the solution.
Drawing on his unsurpassed experience teaching new users, professional data scientist Jared P. Lander has written the perfect tutorial for anyone new to statistical programming and modeling. Organized to make learning easy and intuitive, this guide focuses on the 20 percent of R functionality youâll need to accomplish 80 percent of modern data tasks.
Landerâs self-contained chapters start with the absolute basics, offering extensive hands-on practice and sample code. Youâll download and install R; navigate and use the R environment; master basic program control, data import, manipulation, and visualization; and walk through several essential tests. Then, building on this foundation, youâll construct several complete models, both linear and nonlinear, and use some data mining techniques. After all this youâll make your code reproducible with LaTeX, RMarkdown, and Shiny.
By the time youâre done, you wonât just know how to write R programs, youâll be ready to tackle the statistical problems you care about most.
