Floats is closer to dealing with properties of a vector (norm, distance, etc.). Sample has sophisticated sampling from distributions (metropolis hastings, etc.). gonum&#x2F;stat&#x2F;dist has sampling distributions themselves.<p>Documentation can be found in godoc, i.e. godoc.org&#x2F;github.com&#x2F;gonum&#x2F;stat, godoc.org&#x2F;github.com&#x2F;gonum&#x2F;matrix&#x2F;mat64, etc.
