Scope: column
Family: stat
Returns: number

Argument

columnName (string): The name of the column from which to calculate the entropy.

entropy (number): The Shannon entropy.

Notes

Higher values indicate greater uncertainty or diversity in the distribution of values.
Lower values indicate a more concentrated or predictable distribution.
