template<class TDataset >

void EmptyStatistic< TDataset >::Init	(	const TDataset &	dataset,
		index_t	start,
		index_t	count,
		const EmptyStatistic< TDataset > &	left_stat,
		const EmptyStatistic< TDataset > &	right_stat
	)			[inline]

Initializes by combining statistics of two partitions.

This lets you build fast bottom-up statistics when building trees.
