Detailed Description

Perform quantile normalization.

After a quantile normalization each column has the same distribution of data (the quantiles are the same). Also, within each column the rank of an element is not changed. The distribution that each column follows is determined by taking the average across columns, i.e., the largest element in each column will be equal to the average of the largest elements. The 2nd largest element in each column will be equal to the average of the 2nd largest element in each column et cetera.

There is currently no weighted version of QuantileNormalizer

operator()()

void theplu::yat::normalizer::QuantileNormalizer::operator()	(	const utility::MatrixBase &	matrix,
		utility::MatrixMutable &	result
	)		const

perform the quantile normalization.

It is possible to normalize "in place"; it is permissible for matrix and result to reference to the same Matrix.

Note

dimensions of matrix and result must match.
