In the simplest case, (X, Y) represent data pairs of abscissa and ordinate, in ...
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.
