The ChainedInequality constraint enforces a chain of inequality relationships between any number of columns. For every row, the value in these columns must follow a strict ordering system.
Create a ChainedInequality
constraint.
Parameters:
(required) column_names
: A list of strings that represent the column names. They should appear in ascending order (lowest to highest). Only numerical and datetime columns are allowed.
strict_boundaries
: Whether a column must be strictly greater than previous one
(default) True
: The value in the higher column must be strictly greater than the lower one
False
: The value in the higher column must be greater than or equal to the value of the lower one
table_name
: A string with the name of the table to apply this to. Required if you have a multi-table dataset.
Apply the constraint to any SDV synthesizer. Then fit and sample as usual.
