Understanding the properties of Skew distributions is important in many statistical applications. The Student-t distribution is widely used in statistics. Skew-t distribution is a useful model to describe data with heavy tails. In this paper several

In this work, we discuss m-th exponential spacings △k:m:n obtained from order statistics. We study limit results for such spacings when the sample size n tends to infinity and the indices k and m are either fixed or also tend to infinity. We also i

Different record achievements are fixed in many domains of the human activities. Very often this process happens with some rate of discretization (up to seconds, up to meters or up to thousands of individuals) of the observed results. On the examples

Various record achievements are recorded in a number of areas of human activity. In this case, some discretization of the obtained observation results repeatedly occurs with varying accuracy (up to a second, up to a meter, and up to a thousand indivi

Let X 1 , … , X n be independent and identically distributed continuous nonnegative random variables and m n = min { X 1 , … , X n } be the sample minimum. In the present paper, we find the best li...

Independent random variables X1, X2, . . . , Xn having U([0, 1])-uniform distribution and upper record values in this set are considered. We study the problem of maximizing (taking into account some consecutively observed values x1, x2, . . . , xk of

Let Zi (i ≥ 1) be a sequence of independent and identically distributed random variables with standard exponential distribution H and let Z(n) (n ≥ 1) be the corresponding sequence of exponential records associated with Zi (i ≥ 1). Let us call

Let X1,…,Xn be independent and identically distributed continuous nonnegative random variables and mn be the sample minimum. In the present paper, we propose an approach, which maximizes the value ...

The lower and upper record values obtained from sequences of independent and identically distributed [0, 1] random variables are discussed in this paper. Representations, in which record values are equal in distribution to sums and products of indepe
