a study on rate making and required reserves determination in reinsurance market: a simulation
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
Peakedness and peakedness ordering
The peakedness of a random variable (RV) X about a point a is defined by Pa(x) = P(|X − a| ≤ x), x ≥ 0. A RV X is said to be less peaked about a than a RV Y about b, denoted by X ≤pkd(a,b) Y , if P(|X − a| ≤ x) ≤ P(|Y − b| ≤ x) for all x ≥ 0, i.e., |X − a| is stochastically larger than |Y − b|. These generalize the original definitions of Birnbaum (1948) [2] who considered the cases where X and...
متن کاملconstruction and validation of a computerized adaptive translation test (a receptive based study)
آزمون انطباقی رایانه ای (cat) روشی نوین برای سنجش سطح علمی دانش آموزان می باشد. در حقیقت آزمون های رایانه ای با سرعت بالایی به سمت و سوی جایگزین عملی برای آزمون های کاغذی می روند (کینگزبری، هاوسر، 1993). مقاله حاضر به دنبال آزمون انطباقی رایانه ای برای ترجمه می باشد. بدین منظور دو پرسشنامه مشتمل بر 55 تست ترجمه میان 102 آزمودنی و 10 مدرس زبان انگلیسی پخش گردید. پرسشنامه اول میان 102 دانشجوی س...
Peakedness and peakedness ordering in symmetric distributions
There are many ways to measure the dispersion of a random variable. One such method uses the concept of peakedness. If the random variable X is symmetric about a point μ, then Birnbaum (1948) defined the function Pμ(x) = P (|X − μ| ≤ x), x ≥ 0, as the peakedness of X. If two random variables, X and Y , are symmetric about the points μ and ν, respectively, then X is said to be less peaked than Y...
متن کاملa study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
