Detailed Description

Multivariate cumulative distribution for product symmetric beta density. Can be used as the weight functor with the npstat::mergeTwoHistos function.

Constructor & Destructor Documentation

◆ ProductSymmetricBetaNDCdf()

npstat::ProductSymmetricBetaNDCdf::ProductSymmetricBetaNDCdf	(	const double *	location,
		const double *	scale,
		const double *	power,
		const int *	direction,
		unsigned	dim
	)

The constructor takes array arguments. Each array element is used for one of the dimensions. "dim" gives the size of all arrays as well as the function dimensionality.

location – mean of SymmetricBeta1D in each dimension

scale – scale parameter of SymmetricBeta1D in each dimension

power – power parameter of SymmetricBeta1D in each dimension

direction – a flag which tells us what to do with the cumulative distribution of SymmetricBeta1D. Meanings are as follows: >0 – use exceedance (1 - cdf, weight decreasing) 0 – do not use this dimension at all (factor of 1 will be used everywhere instead of cdf) <0 – use cdf (weight increasing)
