Expand description

Quantile and median aggregation.

Provided Methods§

Source

fn median(&self) -> Option<T>

Returns the mean value in the array. Returns None if the array is empty or only contains null values.

Source

fn quantile( &self, _quantile: f64, _method: QuantileMethod, ) -> Result<Option<T>, PolarsError>

Aggregate a given quantile of the ChunkedArray. Returns None if the array is empty or only contains null values.

Source

fn quantiles( &self, quantiles: &[f64], _method: QuantileMethod, ) -> Result<Vec<Option<T>>, PolarsError>
where T: Clone,

Aggregate a given set of quantiles of the ChunkedArray. Returns None if the array is empty or only contains null values.
