Thank you for your query. Each method have their own assumptions and criterion to apply. You can apply boxplot and z score to single variable but not cooks distance. In this tutorial, I tried to show how to use these methods in R. To know more, you have to learn the theory. Thank you.
Simple and easy 👍
Thank you 😊
why didn't you test a single variable using 3 methods? these results are not comparable and does not explain when to perform what.
