  factor_conversion_threshold = 7
)

Arguments

explainer

cutoff_name

Name for new category that arised after merging entries less frequent than cutoff
factor_conversion_threshold

Numeric columns with lower number of unique values than value of this parameter will be treated as factors

Data frame with columns

  • Variable Name of splited variable
