ols_plot_resid_stand

Standardized residual chart

Chart for identifying outliers.

ols_plot_resid_stand(model, print_plot = TRUE)

`model`	An object of class `lm`.
`print_plot`	logical; if `TRUE`, prints the plot else returns a plot object.

Standardized residual (internally studentized) is the residual divided by estimated standard deviation.

ols_plot_resid_stand returns a list containing the following components:

outliers

a data.frame with observation number and standardized resiudals that exceed threshold

for classifying an observation as an outlier

threshold

threshold for classifying an observation as an outlier

ols_srsd_chart() has been deprecated. Instead use ols_plot_resid_stand().

model <- lm(mpg ~ disp + hp + wt, data = mtcars)
ols_plot_resid_stand(model)
