bool pdf1d_larger_samples	(	const double *	x1,
		int	n1,
		const double *	x2,
		int	n2,
		double	p
	)

Return true if x1[i] significantly larger than x2[j].

Essentially tests if on average a sample from x1 is larger than a proportion p of those from x2

Essentially tests if on average a sample from x1 is larger than one from x2

double pdf1d_prop_larger	(	const double *	x1,
		int	n1,
		const double *	x2,
		int	n2
	)

Return the average number of elements of x2 greater than each x1[i].

int pdf1d_select_largest_samples	(	vcl_vector< const double * > &	x,
		vcl_vector< int > &	n,
		double	p
	)

Select the samples which are on average largest.

x[i] is considered larger than x[j] if on average each element of x[i] is larger than a proportion p of those in x[j]. Where there is ambiguity return smallest index.

Parameters:

x[i]	pointer to data with n[i] elements

Where there is ambiguity return smallest index.

bool pdf1d_smaller_samples	(	const double *	x1,
		int	n1,
		const double *	x2,
		int	n2,
		double	p
	)

Return true if x1[i] significantly smaller than x2[j].

Essentially tests if on average a sample from x1 is smaller than a proportion p of those from x2
