23  NNYFS Case Study

This is nothing worth looking at.

It’s just the start of something. I won’t get to this again until summer 2025. Sorry.

23.1 R setup for this chapter

Note

This section loads all needed R packages for this chapter. Appendix A lists all R packages and data sets used in the book, and also provides R session information. Appendix B describes the 431-Love.R script, and demonstrates its use.

library(knitr)
library(mice)
library(naniar)
library(rstanarm)

library(easystats)
library(tidyverse)

source("data/Love-431.R")
theme_set(theme_bw())

23.2 Data should be NNYFS

Note

Appendix C provides further guidance on pulling data from other systems into R, while Appendix D gives more information (including download links) for all data sets used in this book.
