WebDec 10, 2015 · In this context, the Fisher matrix of the exponential family and a lower bound for arbitrary probabilistic models are discussed. The conservative approximation for Fisher's information matrix rests on a surrogate exponential family distribution connected to the actual data-generating system by two compact equivalences.

This is a companion video to …
When working with this function, it is necessary to set the value of the variable. Immediately it should be noted that there are some situations in which this function will not produce results. This is possible if the variable is: 1. is not a number.

WebJun 26, 2024 · An "observed" information matrix is derived numerically as the hessian by means of optimHess. From the variance-covariance matrix (inverse of the hessian) variation of life(-time) at given quantiles is determined. Application of a bias adjustment alters the calculation of the hessian, thus the bounds are based on a "modified" Fisher Matrix.
