I have a multiple linear regression model with two exposures and four covariates.

Can anyone please clarify my understanding on how to detect influential points?

  1. Run a multiple regression model and use partial regression plots of each of the variables?

  2. Look at the scatterplots of each covariate vs outcome?

In R, there are plots to find the influential points. For example, residual vs leverage plot.

Example: plot(lm(mpg~wt+hp,mtcars))

Details about the plot can be found in

Interpreting plot.lm()
