Expand description

Strategy for missing value injection.

Variants§

MCAR

Missing Completely At Random - each value has equal probability of being missing.

Fields

§probability: f64

Probability of a value being missing (0.0 - 1.0).

MAR

Missing At Random - probability depends on other observed values.

Fields

§base_probability: f64

Base probability.

§conditions: Vec<MissingCondition>

Conditions that increase probability.

MNAR

Missing Not At Random - probability depends on the value itself.

Fields

§value_patterns: Vec<MissingPattern>

Missing probability for specific value ranges/patterns.

Systematic

Systematic missing - entire fields missing for certain records.

Fields

§field_groups: Vec<Vec<String>>

Fields that are systematically missing together.

§probability: f64

Probability of group being missing.
