Errors produced by multivariate analysis operations.

Variants

InsufficientData

Too few observations to perform the analysis.

Fields

min: usize

Minimum number of data points required.

got: usize

Number of data points actually provided.

DimensionMismatch

Series lengths or matrix dimensions do not match.

Fields

expected: usize

Expected dimension size.

got: usize

Actual dimension size.

CycleDetected

The derived-series dependency graph contains a cycle.

SeriesNotFound(String)

The requested series name was not found.

SingularMatrix

The covariance matrix is singular (data may be collinear).

InvalidParameter(String)

A user-supplied parameter is invalid.

Compute(String)

A general computation error.

NotFitted

The model has not been fitted yet.

Trait Implementations

impl Debug for MultivariateError

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

Formats the value using the given formatter.

impl Display for MultivariateError

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

Formats the value using the given formatter.

impl Error for MultivariateError

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.
