Struct LazyStats

Source

pub struct LazyStats<'a, F, D>where
    F: Float,
    D: Data<Elem = F>,
{ /* private fields */ }

Expand description

Lazy statistics calculator that computes values on demand

Implementations§

Source §

impl<'a, F, D> LazyStats<'a, F, D>
where F: Float + NumCast, D: Data<Elem = F>,

Source

pub fn new(data: &'a ArrayBase<D, Ix1>) -> Self

Source

pub fn mean(&self) -> StatsResult<F>

Get mean (computed lazily)

Source

pub fn variance(&self, ddof: usize) -> StatsResult<F>

Get variance (computed lazily)

Source

pub fn minmax(&self) -> StatsResult<(F, F)>

Get min and max (computed together for efficiency)

Source

pub fn median(&self) -> StatsResult<F>

Get median (requires sorting, cached for subsequent quantile calls)

Source

pub fn quantile(&self, q: F) -> StatsResult<F>

Get quantile (uses cached sorted data if available)
