Application of the Wolfs Algorithm in Constructing Effective Portfolios
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)The aim of this paper is to present a method of constructing effective portfolios with application of Wolfs algorithm. The effective portfolios are understood as those which have the lowest risk at give rate of return, ... -

Multidimensional Scaling in Economic Research
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)A relationship between the theoretical terms and the observational ones, called also a perceptual or observational, is essential for scientific research of empirical type, including social sciences and economic sciences. ... -
Probability Model of Ties in Multistage Decision Process
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)Probability model on multistage decision process is discussed with particular emphasis on special case using the rule R(4, 2). An idea of importance graph ties is presented. Possibility recording probability of success in ... -
On Some Robust Against Outhers Predictor of the Total Value in Small Domain
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)he problem of prediction of the total value in a domain based on simple regression superpopulation model (with one auxiliary variable and no intercept) is considered. The problem of robust estimation against outliers of ... -

On Maximization of Estimation Accuracy in Multiparameter Two Stage Sampling
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)In the paper the problem of sample allocation for both stages in such a way, that the accuracy of an estimation of the means of many variables is maximal and the survey cost is restricted is considered. As the measure ... -
On Mean Square Error of Synthetic Regression Estimator
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)The problem of estimation of the total value in a small domain is considered. Because of the small number (or the lack) of elements of the considered subpopulation in the sample, information on all drawn elements is used. ... -
Estimation of Population Averages on the Basis of a Vector of Cluster Means
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)The estimation of a vector of mean values is being considered. The vector estimator consists of simple cluster sample means. It is assumod that a population of a fixed size is divided into mutually disjoint clusters each ... -
Analysis of Censored Life-tables with Covariates by Means of Log-linear Models
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)In survival analysis the subject of observation is duration of time until some event called failure event. Often in such studies only partial information on the length of failure time is available what yields the so-called ... -
Testing the Identity of Distributions of Two Discrete Random Variables
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)The comparing distributions of two discrete random variables appears often in statistical research. In many cases we can apply the test for two means for it. If the means are equal and we do not know the set of values ... -
The Estimate of Power of Random Tests Based on Lenght of Runs
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)Tests based on ienght o f runs are used both in statistical inference and statistical quality assurance. The paper presents power of three tests based on: - maximum run lenght on one side o f the medium, - smaller from ... -
A Two-phase Sampling Strategy for Estimating Multiple Mean Values in the Presence of Nonresponse
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)The phenomenon of nonresponse in sample surveys usually results in biased estimates of population characteristics. One of the means to deal with nonresponse is the subsampling technique. It relies on re-contacting some ... -
Method of Colour Segmentation in Two Dimensional Images
(Wydawnictwo Uniwersytetu Łódzkiego, 2004)The paper is divided into two parts. In the first part an overview of some selected methods of segmenting colours in two dimensional images is given. In the second part a new algorithm is proposed. The new algorithm is ... -
