Function Documentation

double pdf1d_bhat_overlap	(	const pdf1d_pdf &	pdf1,
		const pdf1d_pdf &	pdf2,
		int	n_samples,
		bool	use_analytic
	)

Estimate Bhattacharyya overlap between two pdfs.

If use_analytic is true and an analytic form exists, it will be used. Otherwise n_samples are drawn from pdf1 and used to estimate the overlap
