WebTo have Fisher matrix bounds, a model must have been created by publishing from a data source, such as a Weibull++ or ALTA data sheet, that was calculated using Fisher matrix bounds. Additionally, bounds are not available if the diagram has containers, subdiagrams or mirrored blocks, or if any block uses the cumulative damage model.

"WebThe Fisher information matrix plays a role in an inequality like the isoperimetric inequality. Of all probability distributions with a given entropy, the one whose Fisher information matrix has the smallest trace is the Gaussian distribution. This is like how, of all bounded sets with a given volume, the sphere has the smallest surface area. " - Fisher matrix bounds
