WebFisher scoring (FS) is a numerical method modified from Newton-Raphson (NR) method using score vectors and Fisher information matrix. The Fisher information plays a key role in statistical inference ([8], [9]). NR iterations employ Hessian matrix of which elements comprise the second derivatives of a likelihood function. WebFisher information is one way to measure how much information the samples contain about the parameters. There are alternatives, but Fisher information is the most well known. Before we get to the formal definition, which takes some time to get familiar with, let’s motivate Fisher information with an example. greens daily detox
