Struct ExactNumericAggregates

pub struct ExactNumericAggregates {
    pub min: f64,

Expand description

Exact streaming aggregates for a numeric column: O(1)-memory statistics that an engine computed over the entire stream, as opposed to the bounded sample_values it retained.

Fields§

§min: f64§max: f64§mean: f64§std_dev: f64

Standard deviation with the unbiased (n-1) denominator.

§variance: f64

Variance with the unbiased (n-1) denominator.

§count: usize

Number of parsed numeric values covered by these aggregates.
