corr() [1/2]

template<typename T >

T ttk::Statistics::corr	(	const std::vector< T > &	v1,
		const std::vector< T > &	v2
	)

Compute the sample correlation of two random variables (e.g. two vectors)

Parameters

v1	vector containing the values of the first variable..
v2	vector containing the values of the second variable.

Returns

Returns the correlation of the vectors.

Definition at line 59 of file Statistics.cpp.

corr() [2/2]

template<typename T >

T ttk::Statistics::corr	(	const T *	v1,
		const T *	v2,
		const int &	dimension1 = 3,
		const int &	dimension2 = 3
	)

Compute the sample correlation of two random variables (e.g. two vectors)

Parameters

v1	vector containing the values of the first variable..
v2	vector containing the values of the second variable.
dimension1	Optional parameter that specifies the dimension of the first vector (by default 3).
dimension2	Optional parameter that specifies the dimension of the second vector (by default 3).

Returns

Returns the correlation of the vectors.
