Detailed Description

Forecasts future points from fitted HoltWinters model.

Parameters

[in]	handle	cuml handle to use across the algorithm
[in]	n	n_samples in time-series
[in]	batch_size	number of time-series in X
[in]	frequency	number of periods in a season of the time-series
[in]	h	number of future points to predict in the time-series
[in]	seasonal	type of seasonal component (ADDITIVE or MULTIPLICATIVE)
[out]	level_d	device pointer to array which holds level components
[out]	trend_d	device pointer to array which holds trend components
[out]	season_d	device pointer to array which holds season components
[out]	forecast_d	device pointer to array which will hold the forecast points

Returns: CUML_SUCCESS on success and other corresponding flags upon any failures.
