Struct CurveFitResult 

pub struct CurveFitResult { /* private fields */ }

Implementations

impl CurveFitResult

pub fn builder() -> Builder<R2Stage>

Returns a new builder.

impl CurveFitResult

pub fn r2(&self) -> f64

R^2 (coefficient of determination) for the fit curve, a normalized measure of how well the curve fits the data. Usually ranges from 0 to 1, with higher indicating better fit (points closer to fit line).

pub fn mae(&self) -> f64

Mean Absolute Error (MAE) - the average of the absolute differences between predicted and actual values. Measured in the same units as the y-values.

pub fn mse(&self) -> f64

Mean Squared Error (MSE) - the average of the squared differences between predicted and actual values. Measured in the squared units of the y-values.

pub fn rmse(&self) -> f64

Root Mean Squared Error (RMSE) - the square root of the mean squared error. Measured in the same units as the y-values.

pub fn max_absolute_error(&self) -> f64

Maximum Absolute Error - the largest absolute difference between any predicted and actual value. Measured in the same units as the y-values.

pub fn sample_count(&self) -> i32

The number of data points used in the curve fitting calculation.

pub fn curve_result_details(&self) -> &CurveResultDetails

Description of the fit curve.

Trait Implementations

impl Clone for CurveFitResult

fn clone(&self) -> CurveFitResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CurveFitResult

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CurveFitResult

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CurveFitResult

impl From<CurveFitResult> for Builder<Complete>

fn from(v: CurveFitResult) -> Self

Converts to this type from the input type.

impl Hash for CurveFitResult

fn hash<H: Hasher>(&self, hasher: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CurveFitResult

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CurveFitResult

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

impl PartialOrd for CurveFitResult

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for CurveFitResult

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
