http://boris-belousov.net/2016/10/16/fisher-vs-KL/ WebApr 9, 2024 · The special status of the Fisher–Rao metric in statistics is due to the fact that it is the only metric (up to scaling factors) that has a natural behavior under sufficient statistics (see, e.g., , Theorem 2.6 going back to Chentsov, 1972). Natural behavior of a metric (on the set of probability densities) in this context means informally ...

Webup the Fisher matrix knowing only your model and your measurement uncertainties; and that under certain standard assumptions, the Fisher matrix is the inverse of the covariance matrix. So all you have to do is set up the Fisher matrix and then invert it to obtain the covariance matrix (that is, the uncertainties on your model parameters).
