Member Function Documentation

void theplu::yat::statistics::averager_base< Averager1 >::add	(	double	x,
		long	n = `1`
	)

inlineinherited

add a data point

Adding n number of data point(s) with value x.

void theplu::yat::statistics::averager_base< Averager1 >::add1	(	double	x,
		long int	n
	)

protectedinherited

add n data points with value x

void theplu::yat::statistics::averager_base< Averager1 >::add1 ( double delta )

protectedinherited

add one data point with value delta + mean()

double theplu::yat::statistics::averager_base< Averager1 >::mean ( void ) const

inlineinherited

mean

Returns: Mean of presented data, $\frac{1}{n}\sum x_i$

long theplu::yat::statistics::averager_base< Averager1 >::n ( void ) const

inlineinherited

number of data points

Returns: Number of data points

void theplu::yat::statistics::averager_base< Averager1 >::rescale ( double a )

inlineinherited

Rescales the object.

$\forall x_i \rightarrow a*x_i$ ,

double theplu::yat::statistics::averager_base< Averager1 >::rescale1 ( double x )

protectedinherited

rescale as $mean \rightarrow x mean$

void theplu::yat::statistics::averager_base< Averager1 >::reset ( void )

inlineinherited

Reset object.

Restore Averager as if data were never added

double theplu::yat::statistics::averager_base< Averager1 >::sum_x ( void ) const

inlineinherited

Returns: The sum of data values
