Webas Fisher information, defines a Riemannian metric on the parameter space. This Fisher-Rao metric gives the correct dis-tance between pdfs. If the parameterisation is changed then the description of the Fisher-Rao metric changes but the calculated distance between any two given pdfs remains the same. Maximum likelihood and Fisher information WebMay 1, 2016 · The attractive feature of using the relative Fisher information distance is the result of the expected distance being the expected Fisher information.
