Abstract The present paper proposes shrinkage testimator(s) for the scale parameter for an exponential distribution. An important feature of the proposed testimator is that, it removes the arbitrariness in the choice of shrinkage factor (weights) by making it dependent on the test statistic. The risk properties of the proposed testimator(s) have been studied under asymmetric loss function. It h...

ABSTRICT This paper uses the possibility distribution approach to estimate the insurance loss amount. A special class of parametric possibility distributions is used to model insurance loss variables. The parameters of the possibility distribution are estimated by combining statistical analysis of sample data and domain knowledge provided by actuarial experts. Insurance premiums are calculated ...

We develop two parsimonious models for pricing multi-name credit derivatives. We derive closed form expression for the loss distribution, which then can be used in determining the prices of tranche and index swaps and more exotic derivatives on these contracts. Our starting point is the model of [2], which takes the loss process as a time changed birth process. We introduce stochastic parameter...

the modeling can provide a quantitative approach and consistency in the estimationsoil erosion and sediment yield by a wide range of conditions. in this study, the integration method of revised universal soil loss equation model, geographic information system and remote sensing techniques were used in order to identify the spatial distribution of soil erosion and sediment yield in the talar wat...
