Fisher's Fundamental Theorem of natural selection is one of the most widely cited theories in evolutionary biology. Yet it has been argued that the standard interpretation of the theorem is very different from what Fisher meant to say. What Fisher really meant can be illustrated by looking in a new way at a recent model for the evolution of clutch size. Why Fisher was misunderstood depends, in ...

Miller Fisher syndrome is an uncommon disease and it is a variant of Guillain-Barre syndrome. Miller Fisher syndrome also has rarer variants. Combined features of classic Guillain-Barre syndrome and Miller Fisher syndrome are uncommon. Here we are reporting a case of Miller Fisher variant with Guillain-Barre syndrome overlap in which ataxia, are flexia, oculomotor disturbance and limb weakness ...

Fisher information essentially describes the amount of information data provide about an unknown parameter. It has applications in finding the variance of an estimator, as well as in the asymptotic behavior of maximum likelihood estimates, and in Bayesian inference.

We describe methods to establish identifiability and information-regularity of parameters in normal distributions. Parameters are considered identifiable when they are determined uniquely by the probability distribution and they are information-regular when their Fisher information matrix is full rank. In normal distributions, information-regularity implies local identifiability, but the conver...

Three species of Caribbomerus Vitali are newly recorded for the Dominican Republic: Caribbomerus decoratus (Zayas), Caribbomerus elongatus (Fisher), and Caribbomerus asperatus (Fisher). The first two also represent first records for Hispaniola. Caribbomerus elongatus (Fisher) is redescribed based on additional material, including the first known males. Caribbomerus similis (Fisher) is newly rec...

There is a large literature devoted to the size of the response of nominal interest rates to changes in expected inflation, the Fisher effect. The interest in the topic stems from the implications of the Fisher effect for both asset pricing models and monetary neutrality propositions. Unfortunately no consensus has been achieved concerning the Fisher effect. Part of the problem for this has bee...

In the present paper, we would like to draw attention to a possible generalized Fisher information that ts well in the formalism of nonextensive thermostatistics. This generalized Fisher information is de ned for densities on R. Just as the maximum Rényi or Tsallis entropy subject to an elliptic moment constraint is a generalized qGaussian, we show that the minimization of the generalized Fishe...
