WebA discrete variation of the Fréchet distance that provides good approximations of the continuous measure and can be efficiently computed using a simple algorithm is presented. The Fréchet distance between two curves in a metric space is a measure of the similarity between the curves. We present a discrete variation of this measure. It provides good … One test to assess whether a multivariate distribution is asymptotically dependent or independent consists of transforming the data into standard Fréchet margins using the transformation = / ⁡ and then mapping from Cartesian to pseudo-polar coordinates (,) = (+, / (+)).
