The goal of missr is to help you classify missing data as MCAR, MAR, or MNAR. It does this by providing:

• Statistical tests for MCAR and MAR:
  • mcar()
  • mar()
• Process of elimination for MNAR:
  • mnar()

You can install missr from CRAN:

install.packages("missr")

Or you can install the development version on github using remotes:

# install.packages("remotes")
remotes::install_github("NoahHellen/missr")

• Testing for MCAR.
  • Null hypothesis is that data is MCAR; if the p-value is not significant, there is evidence the data is MCAR.

mcar(data)

• Testing for MAR.
  • Each null hypothesis is that data is not MAR; if each p-value is significant, there is evidence the data is MAR.

mar(data)

• Testing for MNAR.
  • No new tests, simply a process of elimination.

mnar(data)
