WebSu–ciency was introduced into the statistical literature by Sir Ronald A. Fisher (Fisher (1922)). Su–ciency attempts to formalize the notion of no loss of information. A su–cient statistic is supposed to contain by itself all of the information about the unknown parameters of the underlying distribution that the entire sample could have ... 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). fmcna chairside https://gonzojedi.com
