kurtosis with provided mean

Entry point to compute kurtosis with the provided mean values.

Description and Assumptions

The oneapi::mkl::stats::kurtosis function is used to compute an array of kurtosis (kurtosis for each dataset’s dimension) with the provided mean values.

kurtosis with provided mean supports the following precisions for data:

T

float

double

kurtosis with provided mean (buffer version)

Syntax

namespace oneapi::mkl::stats {
template<method Method = method::fast, typename Type,
    layout ObservationsLayout>
    void oneapi::mkl::stats::kurtosis(sycl::queue& queue,
    sycl::buffer<Type, 1> mean,
    const oneapi::mkl::stats::dataset<sycl::buffer<Type, 1>, ObservationsLayout>& data,
    sycl::buffer<Type, 1> kurtosis);
}

Template Parameters

Method

Method which is used for estimate computation. The specific values are as follows:

  • oneapi::mkl::stats::method::fast

Type

Data precision.

ObservationsLayout

Data layout. The specific values are described in dataset.

Input Parameters

queue

The queue where the routine should be executed.

mean

sycl::buffer to the array of provided mean values.

data

Dataset which is used for computation.

Output Parameters

kurtosis

sycl::buffer array of kurtosis values.

Throws

oneapi::mkl::invalid_argument

Exception is thrown when kurtosis.get_count() == 0, or mean.get_count() == 0, or dataset object is invalid

kurtosis with provided mean (USM version)

Syntax

namespace oneapi::mkl::stats {
template<method Method = fast, typename Type, layout ObservationsLayout>
    sycl::event kurtosis(sycl::queue& queue,
    Type* mean,
    const dataset<ObservationsLayout, Type*>& data,
    Type* kurtosis,
    const std::vector<sycl::event> &dependencies = {});
}

Template Parameters

Method

Method which is used for estimate computation. The specific values are as follows:

  • oneapi::mkl::stats::method::fast

Type

Data precision.

ObservationsLayout

Data layout. The specific values are described in dataset.

Input Parameters

queue

The queue where the routine should be executed.

mean

Pointer to the array of provided mean values.

data

Dataset which is used for computation.

dependencies

Optional parameter. List of events to wait for before starting computation, if any.

Output Parameters

kurtosis

Pointer to the array of the kurtosis values.

Throws

oneapi::mkl::invalid_argument

Exception is thrown when kurtosis == nullptr, or mean == nullptr, or dataset object is invalid

Return Value

Output event to wait on to ensure computation is complete.
