Enum QQDistribution 

pub enum QQDistribution {
    Normal {
        mean: f64,
        sd: f64,
    },
    StudentT {
        df: f64,
    },
    Exponential {
        rate: f64,
    },
    HalfNormal {
        sd: f64,
    },
}

Theoretical distribution of a QQ plot, with its parameters (ggplot2’s distribution + dparams).

Variants

Normal

Normal (qnorm), default mean = 0, sd = 1.

Fields

mean: f64

sd: f64

StudentT

Student t (qt) with df degrees of freedom.

Fields

df: f64

Exponential

Exponential (qexp) with the given rate.

Fields

rate: f64

HalfNormal

Half-normal — |Z|·sd, the reference for half-normal plots of absolute residuals: quantile sd · qnorm((1 + p) / 2).

Fields

sd: f64

Implementations

impl QQDistribution

pub fn normal() -> Self

Standard normal.

pub fn t(df: f64) -> Self

Student t with df degrees of freedom.

pub fn exponential() -> Self

Exponential with rate 1.

pub fn half_normal() -> Self

Half-normal with sd = 1.

pub fn quantile(&self, p: f64) -> f64

Quantile function (q* in R). NaN for invalid parameters.

pub fn density(&self, x: f64) -> f64

Density (d* in R) — the pointwise band’s standard error uses it.
