Maximizable informational entropy as a measure of probabilistic uncertainty. (English) Zbl 1203.82004

Summary: We consider a recently proposed entropy \(S\) defined by a variational relationship \(dI = d\bar x - \overline{dx}\) as a measure of uncertainty of random variable \(x\). The entropy defined in this way underlies an extension of virtual work principle \(\overline{dx} = 0\) leading to the maximum entropy \(d(I - \bar x)\). This paper presents an analytical investigation of this maximizable entropy for several distributions such as the stretched exponential distribution, \(\kappa \)-exponential distribution, and Cauchy distribution.
