Function variance 

Source 
pub fn variance<T, D>(
    array: &ArrayView<'_, T, D>,
    axis: Option<Axis>,
    ddof: usize,
) -> Result<Array<T, Ix1>, &'static str>
where
    T: Clone + Float + FromPrimitive,
    D: Dimension + RemoveAxis,
Expand description

Calculate the variance of array elements

§Arguments

  • array - The input array
  • axis - Optional axis along which to compute the variance (None for global variance)
  • ddof - Delta degrees of freedom (default 0)

§Returns

The variance of the array elements

§Errors

Returns an error if the array is empty or if conversion fails.

§Panics

Panics if type conversion from usize fails.
