Fisher information negative binomial
WebIn statistics, the observed information, or observed Fisher information, is the negative of the second derivative (the Hessian matrix) of the "log-likelihood" (the logarithm of the likelihood function). It is a sample-based version of the Fisher information. Definition[edit] Webwith respect to do not depend on Y, so the Fisher information is always given by r 2l( ) without needing to take an expectation. (We sometimes say in this case that the \observed and expected Fisher information matrices" are the same.) On the other hand, from the modeling perspective, there is usually no intrinsic reason to believe that the ...

This is easy since, according to Equation 2,5 and the definition of Hessian, the negative Hessian of the loglikelihood function is the thing we are looking for. You might question why is the Fisher information matrix in Eq 2.5 the same as the Hessian, though it is an expected value?
