Hyperbolic cosine ratio and hyperbolic sine ratio random fields
(Elsevier, 202112)This paper introduces several vector random fields whose finitedimensional characteristic functions are of hyperbolic type, including generalized logistic, hyperbolic secant, hyperbolic tangent, hyperbolic cosine ratio, ... 
Kcombined random fields: Basic properties and stochastic orderings
(Taylor and Francis, 20210517)This paper introduces the Kcombined vector random field, whose finitedimensional characteristic functions are made up of certain power functions and whose finitedimensional density functions are comprised of the modified ... 
Peakedness and convex ordering for elliptically contoured random fields
(Elsevier, 201812)For the peakedness comparison between two Gaussian random fields about their mean functions, a necessary and sufficient condition is derived in this paper in terms of their covariance functions. interestingly, such a ... 
Peakedness and peakedness ordering
(Elsevier, 20120510)The peakedness of a random variable (RV) X about a point a is defined by . 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 ... 
Stochastic comparison for elliptically contoured random fields
(Elsevier, 20221001)This paper presents necessary and sufficient conditions for the peakedness comparison and convex ordering between two elliptically contoured random fields about their centers. A somewhat surprising finding is that the ...
