Residual vs regressor plot

Description

Graph to determine whether we should add a new predictor to the model already containing other predictors. The residuals from the model is regressed on the new predictor and if the plot shows non random pattern, you should consider adding the new predictor to the model.

Usage

ols_plot_resid_regressor(model, variable, print_plot = TRUE)

Arguments

model	An object of class lm.
variable	New predictor to be added to the model.
print_plot	logical; if TRUE, prints the plot else returns a plot object.
