Function var_v2 

pub fn var_v2<T>(
    arr: &Array<T>,
    bias_kind: VarianceBias,
    dim: i64,
) -> Array<T::MeanOutType>
where
    T: HasAfEnum,
    T::MeanOutType: HasAfEnum,

Compute Variance along a specific dimension

Parameters

• arr is the input Array
• bias_kind of type VarianceBias denotes the type of variane to be computed
• dim is the dimension along which the variance is extracted

Return Values

Array with variance of input Array arr along dimension dim.
