Detailed Description

Zero mean and unity variance.

Shift and scale the values in a range as: $y_i = \frac{x_i-m}{s}$ where m is the mean and s is the standard deviation. After normalization, the range will have zero mean and unity variance.

Type Requirements:

InputIterator is Data Iterator
InputIterator is Forward Traversal Iterator
OutputIterator is Writable Iterator
OutputIterator is Forward Traversal Iterator

Since: New in yat 0.5

void theplu::yat::normalizer::Zscore::operator()	(	InputIterator	first,
		InputIterator	last,
		OutputIterator	result
	)		const

inline

The element in range [result, result + (last-first)) is calculated as result[i] = (first[i] - m) / s where m and std are the mean and standard deviation, respectively, of the range [first, last).

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