Usage

check_residuals(object, ...)

object

An object of class 'explainer' created with function explain from the DALEX package.

...

other parameters that will be passed to further functions.

Value

list with statistics for particular checks

Examples

dragons <- DALEX::dragons[1:100, ]
lm_model <- lm(life_length ~ ., data = dragons)
lm_audit <- audit(lm_model, data = dragons, y = dragons$life_length)
check_residuals(lm_audit)
 ## Not run: 
 library("randomForest")
 rf_model <- randomForest(life_length ~ ., data = dragons)
 rf_audit <- audit(rf_model, data = dragons, y = dragons$life_length)
 check_residuals(rf_audit)
