Rare Value Suppression
← Back
Current dataset: (none)
Scope
Choose whether to scan all columns or only the columns you pick below.
Rare values are detected per column.
Threshold
- By minimum count: treat values appearing fewer than m times as rare.
- By minimum proportion: treat values with frequency below p% as rare.
Generalization Settings
Customize how rare values are generalized by type. Numeric options
support fixed-width binning, rounding, or quantile binning (per-column
based on observed distribution). Date options control time granularity.
String options control how characters are masked or truncated.
Rarity Preview
This preview estimates how many rows/values will be affected given your current scope and thresholds. It updates automatically when you change settings.
Action
Choose how to handle rare values: mask cells with
*, drop
rows entirely, or generalize values (use settings above).
