Struct NumericStats 

pub struct NumericStats {
    pub mean: f64,
    pub std: f64,
    pub five: FiveNumber,
    pub skewness: f64,
    pub kurtosis: f64,
    pub histogram: Histogram,
    pub outlier_count: usize,
    pub outlier_fraction: f64,
}

The descriptive statistics computed for a numeric column.

Missing values (NaN) are excluded from every statistic and counted separately in ColumnProfile::missing_count.

Fields

mean: f64

Arithmetic mean of the non-missing values (NaN if the column is empty).

std: f64

Sample standard deviation (ddof = 1) of the non-missing values.

five: FiveNumber

Min/Q1/median/Q3/max of the non-missing values.

skewness: f64

Fisher–Pearson sample skewness of the non-missing values (0.0 when undefined, i.e. fewer than three values or zero variance).

kurtosis: f64

Excess (Fisher) kurtosis of the non-missing values (0.0 when undefined, i.e. fewer than four values or zero variance).

histogram: Histogram

Equal-width histogram (Sturges bins) of the non-missing values.

outlier_count: usize

Number of values outside the Tukey IQR fences (Q1 − 1.5·IQR, Q3 + 1.5·IQR).

outlier_fraction: f64

Fraction of values outside the IQR fences, in [0.0, 1.0].
