Reexpress McElreath’s "Statistical Rethinking" (2015) by fitting the models in brms, plotting with ggplot2, and data wrangling with tidyverse-style syntax. And brms has only gotten better over time. bayesplot: Plotting for Bayesian models. I reproduce the bulk of the figures in the text, too. Sometimes this is through the removal of "outliers," cases in the data that offend the model and are exiled. I’m also assuming you understand the rudiments of R and have at least a vague idea about what the tidyverse is. I love McElreath's Statistical rethinking text.However, I've come to prefer using Bürkner’s brms package when doing Bayesian regression in R. It's just spectacular.I also prefer plotting with Wickham's ggplot2, and using tidyverse-style syntax (which you might learn about here or here).. (2019). His models are re-fit in brms, plots are redone with ggplot2, and the general data wrangling … Though not all within the R community share this opinion, I am among those who think the tidyverse style of coding is generally easier to learn and sufficiently powerful that these packages can accommodate the bulk of your wrangling data needs. This project is not meant to stand alone. I follow the structure of his text, chapter by chapter, translating his analyses into brms and tidyverse code. https://clauswilke.com/dataviz/, Xie, Y. His models are re-fit with brms, the figures are reproduced or reimagined with ggplot2, and the general data wrangling code now predominantly follows the tidyverse style. https://doi.org/10.18637/jss.v080.i01, Bürkner, P.-C. (2018). And of course, the widely-used ggplot2 package is part of the tidyverse, too. This project is an attempt to re-express the code in McElreath’s textbook. So in the meantime, I believe there’s a place for both first and second editions of his text. A Solomon Kurz. Happily, in recent years Hadley Wickham and others have been developing a group of packages collectively called the tidyverse. It’s a pedagogical boon. Though the second edition kept a lot of the content from the first, it is a substantial revision and expansion. http://mjskay.github.io/tidybayes, Kurz, A. S. (2020b). I also imagine working data analysts might use this project in conjunction with the text as they flip to the specific sections that seem relevant to solving their data challenges. With the help of others within the community, I corrected many typos and streamlined some of the code (e.g.. And in some cases, I corrected sections that were just plain wrong (e.g., some of my initial attempts in section 3.3 were incorrect). https://doi.org/10.1111/rssa.12378, Gelman, A., Goodrich, B., Gabry, J., & Vehtari, A. Advanced Bayesian multilevel modeling with the R package brms. It’s flexible, uses reasonably-approachable syntax, has sensible defaults, and offers a vast array of post-processing convenience functions. I did my best to check my work, but it’s entirely possible that something was missed. And I can also offer glimpses of some of the other great packages in the R + Stan ecosystem, such as loo (Vehtari, Gabry, et al., 2019; Vehtari et al., 2017; Yao et al., 2018), bayesplot (Gabry et al., 2019; Gabry & Mahr, 2019), and tidybayes (Kay, 2020b). As a result, the plots in each chapter have their own look and feel. https://ggplot2-book.org/, Wickham, H. (2019). Hopefully you will, too.
