Studies in the field of wage and income distribution concentrate on measuring income inequality. We can investigate both the inequality within the population and the inequality between the populations. The latter can be ...

It is well known that nonparametric regression techniques do not have good performance in high dimensional regression. However nonparametric regression is successful in one- or low-dimensional regression problems and is ...

In tins paper we present a method which is able to identify the degrees of the matrix polynomials that are involved in the VARMA models. This method is based on the difference between the ranks of certain matrices defined ...

In this paper we present some problems concerning artificial intelligence. In the first two points there are presented algorithmic and heuristic procedures, which are applied in solving problems and making optimal decision ...

This paper presents some important earlier results of the research concerning the properties of the distribution of the quotient of random variables. We present also our own ideas and results of the research concerning ...

In many statistical tasks a necessity of testing multivariate normality arises. In constructing multivariate normality tests there is a necessity of estimating unknown parameters ц and £ from a given sample. The parameters ...

The purpose of this paper is to carry out the Bayesian analysis of a two-phase regression model with an unknown break point. Essentially, there are two problems associated with a changing linear model. Firstly, one will ...

In the present paper we discuss a doubly truncated generalized gamma distribution and give formulae for the moments of this distribution and special cases together with examples of calculations.

In this paper the verification of hypotheses of univariate normality by Durbin randomized method is presented. The method of elimination of the nuisance parameters by calculating the residual vector and connected residual ...
