The planning and design of future experiments rely heavily on forecasting to assess the potential scientific value provided by a hypothetical set measurements. Fisher information matrix, due its convenient properties low computational cost, provides an especially useful tool. However, matrix only reasonable approximation true likelihood when data are nearly Gaussian distributed observables have...

A Fisher market is an economic model of buyer and seller interactions in which each buyer’s utility depends only on the bundle goods she obtains. Many people’s interests, however, are affected by their social with others. In this paper, we introduce a generalization markets, namely influence captures impact buyers’ utilities. We show that competitive equilibria markets correspond to generalized...

This paper provides a systematic approach to semiparametric identification that is based on statistical information as measure of its “quality.” Identification can be regular or irregular, depending whether the Fisher for parameter positive zero, respectively. I first characterize these cases in models with densities linear an infinite-dimensional parameter. then introduce novel “generalized in...

A classic theorem in combinatorial design theory is Fisher’s inequality, which states that a family F of subsets of [n] with all pairwise intersections of size λ can have at most n non-empty sets. One may weaken the condition by requiring that for every set in F , all but at most k of its pairwise intersections have size λ. We call such families k-almost λ-Fisher. Vu was the first to study the ...
