Enum NormalityError 

pub enum NormalityError {
    NonFinite,
    InsufficientData {
        need: usize,
        got: usize,
    },
    ZeroVariance,
    ZeroRange,
}

Why a residual-distribution diagnostic could not be computed.

Variants

NonFinite

A residual was non-finite.

InsufficientData

Fewer residuals than the statistic needs (the required minimum is reported).

Fields

need: usize

Minimum number of residuals the statistic requires.

got: usize

Number of residuals supplied.

ZeroVariance

The residual set has zero (or numerically zero) variance, so a moment ratio is undefined.

ZeroRange

The residual set has zero range (all values equal), so the Shapiro-Wilk statistic is undefined.

Trait Implementations

impl Clone for NormalityError

fn clone(&self) -> NormalityError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NormalityError

impl Debug for NormalityError

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

Formats the value using the given formatter.

impl Display for NormalityError

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

Formats the value using the given formatter.

impl Eq for NormalityError

impl Error for NormalityError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for NormalityError

fn eq(&self, other: &NormalityError) -> 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.
