Struct GaussianDistribution 

pub struct GaussianDistribution { /* private fields */ }

👎Deprecated since 54.0.0:

Part of the unused Statistics V2 framework; see https://github.com/apache/datafusion/pull/22071

Gaussian (normal) distribution, represented by its mean and variance. For a more in-depth discussion, see:

Implementations

impl GaussianDistribution

pub fn data_type(&self) -> DataType

pub fn mean(&self) -> &ScalarValue

pub fn variance(&self) -> &ScalarValue

pub fn median(&self) -> &ScalarValue

pub fn range(&self) -> Result<Interval>

Trait Implementations

impl Clone for GaussianDistribution

fn clone(&self) -> GaussianDistribution

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GaussianDistribution

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for GaussianDistribution

fn eq(&self, other: &GaussianDistribution) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
