Functions
Value	nk::stats::pdist (const Value &X, const std::string &metric, double p, std::pmr::memory_resource *mr=nullptr)
	Pairwise distances between rows of X (d = pdist(X, metric, p)).
Value	nk::stats::pdist2 (const Value &X, const Value &Y, const std::string &metric, double p, std::pmr::memory_resource *mr=nullptr)
	Cross-set pairwise distances (D = pdist2(X, Y, metric, p)).
Value	nk::stats::squareform (const Value &d, std::pmr::memory_resource *mr=nullptr)
	Pack / unpack the pdist row form (Y = squareform(d)).
Value	nk::stats::mahal (const Value &Y, const Value &X, std::pmr::memory_resource *mr=nullptr)
	Mahalanobis distance squared (d² = mahal(Y, X)).
