WebThe whole point of the Fisher matrix formalism is to predict how well the experiment will be able to constrain the model parameters, before doing the experiment and in fact without even simulating the experiment in any detail. We can then forecast the results of di erent … WebAbstract. The Fisher informational metric is unique in some sense (it is the only Markovian monotone distance) in the classical case. A family of Riemannian metrics is called monotone if its members are decreasing under stochastic mappings. These are the metrics to play the role of Fisher metric in the quantum case.
