Detailed Description

Class for taking care of mean and covariance of two variables.

Constructor & Destructor Documentation

theplu::yat::statistics::AveragerPair::AveragerPair ( const AveragerPair & )

The copy constructor

void theplu::yat::statistics::AveragerPair::add	(	const double	x,
		const double	y,
		const long	n = `1`
	)

Adding n pairs of data points with value x and y.

double theplu::yat::statistics::AveragerPair::ccc ( void ) const

Concordence correlation coefficient.

$\frac{\sum_i (x_i-m_x)(y_i-m_y)}{\sum_i (x_i-m_x)^2+\sum_i (y_i-m_y)^2 + n(m_x-m_y)^2}$

double theplu::yat::statistics::AveragerPair::correlation ( void ) const

$\frac{\sum_i (x_i-m_x)(y_i-m_y)}{\sqrt{\sum_i (x_i-m_x)^2\sum_i (y_i-m_y)^2}}$

  \return %Pearson correlation coefficient.

double theplu::yat::statistics::AveragerPair::covariance ( void ) const

Calculating covariance using $\frac{1}{N}\sum_i (x_i-m_x)(y_i-m_y)$ , where $ m $ is the mean.

double theplu::yat::statistics::AveragerPair::mean_xy ( void ) const

double theplu::yat::statistics::AveragerPair::msd ( void ) const

Returns:: Average squared deviation between x and y $\frac{1}{N} \sum (x-y)^2$

long theplu::yat::statistics::AveragerPair::n ( void ) const

const AveragerPair& theplu::yat::statistics::AveragerPair::operator+= ( const AveragerPair & )
