Application of Dagum economic distances to the analysis of wage distributions in Poland
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)
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 ...
Asymptotic results for sliced inverse regression
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)
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 ...
Characterization o f the orders in VARMA models
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)
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 ...
Remarks on some learning algorithms
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)
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 ...
The distribution and parameters of the distribution of the quotient of random variables
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)
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 ...
The verification of the multivariate normal distribution hypothesis in a one-sample model with the method of elimination of disturbing parameters
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)
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 ...
Bayesian estimation of a shift point in a two-phase regression model
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)
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 ...
Remarks on the generalized doubly truncated gamma distribution
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)
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.
Usefullness of Durbin method for investigating normality in one-dimensional linear model
(Wydawnictwo Uniwersytetu Łódzkiego, 1997)
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 ...
