Let X be a random variable from a normal distribution with unknown mean θ and known variance σ2. In many practical situations, θ is known in advance to lie in an interval, say [−m,m], for some m > 0. As the usual estimator of θ, i.e., X under the LINEX loss function is inadmissible, finding some competitors for X becomes worthwhile. The only study in the literature considered the problem of min...
This work establishes exact formulae for the persistence probabilities pk(θ)=P[Y1⩾0,…,Yk⩾0] of an AR(1) sequence Yn=θYn−1+Xn, n=1,2,… with parameter θ∈R﹨(12,2) and symmetric uniform innovations Xn. The are in terms certain polynomials, most notably a family that arises case −1<θ<12 was introduced by Mallows Riordan very different context counting finite labeled trees when ordered inversions. co...
in this paper we study the relation between module amenability of θ - lau product a×θb and that of banach algebras a, b. we also discuss module biprojectivity of a×θb. as a consequent we will see that for an inverse semigroup s, l 1 (s) ×θ l 1 (s) is module amenable if and only if s is amenable.
The censored data are widely used in statistical tests and parameters estimation. In some cases e.g. medical accidents which data are not recorded at the time of occurrence, some methods such as interval censoring are used. In this paper, for a random sample uniformly distributed on the interval (0,θ) the interval censoring have been used. A consistent estimator of θ and some asy...
