Gmm fisher
WebNow, the observed Fisher Information Matrix is equal to $(-H)^{-1}$. The reason that we do not have to multiply the Hessian by -1 is that the evaluation has been done in terms of -1 times the log-likelihood. This means that the Hessian that is produced by optim is already multiplied by -1. Share. WebFisher Vector Encoding.
