Errors from building a Pearson representation.

Variants

InvalidMoments

A moment is not finite, or the standard deviation is not positive.

Fields

mean: f64

Mean.

std_dev: f64

Standard deviation.

skewness: f64

Skewness.

kurtosis: f64

Kurtosis.

OutsideTypeIv

(γ, β) is outside the Pearson type IV region.

Fields

skewness: f64

Skewness γ.

kurtosis: f64

Kurtosis β.

min_kurtosis: Option<f64>

The boundary β_IV(γ); None when γ^2 >= 32 (no type IV distribution has that skewness).

BadHistogram(String)

The histogram has too few counts or bins to fit.

Trait Implementations

impl Clone for PearsonError

fn clone(&self) -> PearsonError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PearsonError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PearsonError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PearsonError

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

Formats the value using the given formatter.

impl Error for PearsonError

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 PearsonError

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for PearsonError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
