Suppose {Xi,i≥1} and {Yi, i≥1} are two independent sequences with distribution functions and , respectively. Zi,n is the combination of Xi and Yi with a probability for each I with 1≤ i≤n. The extreme value distribution GZ(x) of this particular triangular array of the i.i.d. Random variables Z1,n,… Z2,n, Zn,n is discussed. We found a new form of the extreme value distributions i)ΦAα1(x)Φα2 and ii) ψAα(x)ψα2(x)α1<α2), which are not max-stable. It occurs if FX and FY belong to the same MDA(Φ) or MDA(Ψ).  相似文献   

Extreme value distributions of mixing two sequences with different MDA''s     

蒋岳祥 《浙江大学学报(A卷英文版)》2004,5(5)

Suppose {Xi, i≥1} and {Yi, i≥1} are two independent sequences with distribution functions FX(x) and FY(x), respectively. Zi,n is the combination of Xi and Yi with a probability pn for each i with 1≤i≤n. The extreme value distribution GZ(x) of this particular triangular array of the i.i.d. random variables Z1,n , Z2,n ,…, Zn,n is discussed. We found a new form of the extreme value distribution (A(ρx)(ρx)(0<ρ<1), which is not max-stable. It occurs if FX(x) and FY(x) belong to the same MDA(ρ). GZ(x) does not exist as mixture forms of the different types of extreme value distributions.  相似文献

A class of not max-stable extreme value distributions     

蒋岳祥 《浙江大学学报(A卷英文版)》2005,6(4):315-321

The sequences {Zi,n, l≤i≤n}, n≥l have multi-nomial distribution among i.i.d. random variables {X1,i, i≥1}, {X2,i,u≥l }, …, {Xm,i, i≥1 }. The extreme value distribution Gz(x) of this particular triangular array of i.i.d, random variables Z1,n, Z2Zn,n is discussed in this paper. We found a new type of not max-stable extreme value distributions, i) Gz(x) = r-1∏i=1ФAiαi(x) × Фαr (x);ii) Gz (x) = r-1∏i=1ψAiαi (x) × ψαr (x); iii) Gz (x) = r-1∏i=1 ∧Ai (λix) × A(x), r≥2, 0＜α1≤α2≤…≤αr and λi∈ (0,1] for i, l≤i≤r-1 which occur if Fj, …, Fm belong to the same MDA.  相似文献

INTRODUCTION Let {Xi, i ≥1} and {Yi, i ≥1} be two independ-ent sequences of independent and identicallydistributed random variables with distribution func-tions FX(x)∈MDA(GX) and FY(x)∈MDA(GY), res-pectively. We deal with the case when {Zi , 1≤i≤n},nis a mixture of two independent sequences {Xi, i≥1}and {Yi, i≥1}, for pn∈[0, 1) which is defined by: Zi,n = ???Yi Xi with probability pn with probability 1? pn.We consider the extreme value distribution GZ(x) of{Zi , 1≤i≤n}…  相似文献

Soft power: From ethnic attraction to national attraction in sociological globalism     

Seong-Hun Yun  Jeong-Nam Kim   《Int J Intercult Relat》2008,32(6):565-577

This paper explores the influence of ethnic relations in sociological globalism on the formulation process of a country’s soft power (i.e., national attraction). People migrate into a country, become an ethnic group, and experience sociological contact/interaction with other ethnic groups, through which they form more concrete and experiential attitudes toward each other. In turn, these attitudes affect their perceptions of other ethnic groups’ homeland countries. With soft power being defined as favorability toward a foreign country, this paper investigates the influence of ethnic relations in a three-predictor regression model of soft power—ethnic relations, between country relationship quality, and normative performance (i.e., reputation) of a country. In testing the model, this study uses secondary data consisting of U.S. national surveys including polls of the Chicago Council on Foreign Relations on perceptions of foreign countries and aggregate nation-level data. The findings show that ethnic relations has a sizable, significant influence on favorability, second to relationship quality, with normative performance having a weak, insignificant influence. This paper further discusses the findings’ implications for contemporary public diplomacy practice and theory and outlines directions for future study of ethnic relation’s influence on soft power in sociological globalism.  相似文献   

人际吸引中性别助长效应的实验研究     

宋春蕾  殷玮  陆胜男 《苏州教育学院学报》2012,29(5):77-79

采用“情景剧本”法,探完了不同来源自我描述（中心描述、边缘描述）和不同性质自我描述（极力正向描述、反自身利益描述）情境中人际吸引的性别助长效应。实验结果发现：“边缘描述”比“中心描述”更能促进人际吸引：性别在“中心描述”与“边缘描述”中具有不同的助长效应。  相似文献
