library(tidyverse)
library(missCompare)

Learning goals

  • Explain the difference between MCAR, MAR, and MNAR missing data mechanisms and how the missing data mechanism affects the choice of imputation method
  • Use the missCompare package to identify the optimal imputation algorithm for a particular dataset

We’ll be looking at the vignette (tutorial) in the missCompare package. To view the vignette, we can look at the online version or install the missCompare package and view the vignette after installation:

install.packages("BiocManager")
BiocManager::install("pcaMethods")
install.packages(c("missCompare", "pcaMethods"))
