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). WebJun 1, 2024 · As a final remark, let us mention another method that could be employed to obtain a generalization of the Fisher metric. Instead of replacing the standard logarithm by the group logarithm in the relative entropy to get the relative group entropy and then derive the group Fisher metric, one could do this replacement in the standard Fisher metric …
