ols_plot_resid_stand function

Standardized residual chart

Chart for identifying outliers.

ols_plot_resid_stand(model, threshold = NULL, print_plot = TRUE)

Arguments

• model: An object of class lm.
• threshold: Threshold for detecting outliers. Default is 2.
• print_plot: logical; if TRUE, prints the plot else returns a plot object.

Returns

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

Details

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

Examples

model <- lm(mpg ~ disp + hp + wt, data = mtcars)
ols_plot_resid_stand(model)
ols_plot_resid_stand(model, threshold = 3)
