ols_plot_resid_stud_fit: Deleted studentized residual vs fitted values plot
In cmlopera/olsrr: Tools for Building OLS Regression Models

Description Usage Arguments Details Value Deprecated Function See Also Examples

Plot for detecting violation of assumptions about residuals such as non-linearity, constant variances and outliers. It can also be used to examine model fit.

model

An object of class lm.

Studentized deleted residuals (or externally studentized residuals) is the deleted residual divided by its estimated standard deviation. Studentized residuals are going to be more effective for detecting outlying Y observations than standardized residuals. If an observation has an externally studentized residual that is larger than 2 (in absolute value) we can call it an outlier.

ols_plot_resid_stud_fit returns a list containing the following components:

`outliers`	a tibble with observation number, fitted values and deleted studentized residuals that exceed the `threshold` for classifying observations as outliers/influential observations
`threshold`	`threshold` for classifying an observation as an outlier/influential observation

ols_dsrvsp_plot() has been deprecated. Instead use ols_plot_resid_stud_fit().
