Detailed Description

Replace elements with normalized rank.

Each element x is replaced by $\frac{\sum I(x_i-x) w_i}{\sum w_i}$ where $ I(x) = 1 $ for $ x>0 $ , $I(x) = 0.5 $ for $ x=0 $ , and $ I(x) = 0 $ for $ x<0 $ .

Member Function Documentation

template<typename RandomAccessIter1, typename RandomAccessIter2>

void theplu::yat::normalizer::Spearman::operator()	(	RandomAccessIter1	first,
		RandomAccessIter1	last,
		RandomAccessIter2	result
	)			const `[inline]`

It is possible to centralize a range "in place"; it is permissible for the iterators first and result to be the same.

Type Requirements:

RandomAccessIter1 must be a Random Access Iterator
RandomAccessIter2 must be a mutable Random Access Iterator
