Get a mask of all the duplicated values.

pub fn value_counts(&self) -> Result<DataFrame>

Count the unique values.

pub fn n_unique(&self) -> Result<usize>

Number of unique values in the ChunkedArray

impl ChunkVar<f64> for Float64Chunked

pub fn var(&self) -> Option<f64>

Compute the variance of this ChunkedArray/Series.

pub fn std(&self) -> Option<f64>

Compute the standard deviation of this ChunkedArray/Series.

impl IntoGroupTuples for Float64Chunked

pub fn group_tuples(&self) -> Vec<(usize, Vec<usize>)>
