the aim of the present study was the estimation of (co) variance components and genetic parameters for body weight of moghani sheep, using random regression models based on b-splines functions. the data set included 9165 body weight records from 60 to 360 days of age from 2811 moghani sheep, collected between 1994 to 2013 from jafar-abad animal research and breeding institute, ardabil province,...

We present a robust version of the life-cycle optimal portfolio choice problem in presence labor income, as introduced Biffis, Gozzi, and Prosdocimi [SIAM J. Control Optim., 58 (2020), pp. 1906--1938] Dybvig Liu [J. Econom. Theory, 145 (2010), 885--907]. In particular, influence past wages on future ones is modeled linearly evolution equation through given weight function. The optimization reli...

the objectives of this study were to identify a suitable mathematical model for describing the growth curve of baluchi sheep based on monthly records of live weight from birth to yearling; and to evaluate the efficacies of nonlinear mixed effect model (nlmm) and the nonlinear fixed effect model (nlm) methodologies. growth models were fitted to a total of 16,650 weight–age data belonging to 2071...

Environmental quality evolution and environmental policy involve uncertainties in various dimensions. These uncertainties can often not be represented by a unique, probabilistic belief and thus standard expected utility preferences representation models can not be used for the determination of optimal mitigation and adaptation decisions. Several alternatives for the expected utility model have ...

We introduce a new theory of belief revision under ambiguity. It is recursive (random variables are evaluated by backward induction) and consequentialist (the conditional expectation any random variable depends only on the values attains conditioning event). Agents experience no change in preferences but sensitive to timing resolution uncertainty. provide three main theorems: first characterize...

We provide revealed preference axioms that characterize models of translation invariant preferences. In particular, we characterize the models of variational, maxmin, CARA and CRRA utilities. In each case we present a revealed preference axiom that is satisfied by a dataset if and only if the dataset is consistent from the corresponding utility representation. Our results complement traditional...
