Method var

static member var: Tensor<'T> * int64 option -> 'T

Calculates the variance of the tensor.

Declaration
static member var: a:Tensor<'T> * ddof:int64 option -> 'T
Parameters
Type Name Description
Tensor<'T> a

The tensor containing the source values.
int64 option ddof
Returns
Type Description
'T

The variance estimate.
Remarks

The variance is calculated over all elements of the tensor.

The parameter ddof specifies the difference between the number of elements and the degrees of freedom for the computation of the variance. Use ddof=1 to obtain an unbiased estimate and ddof=0 for a maximum-likelihood estimate.

Examples
 let a = HostTensor.ofList2D [[1.0; 2.0; 3.0; 4.0]
                              [5.0; 6.0; 7.0; 8.0]]
 let b = Tensor.var a
