In the area of image analysis of templates, we have proposed and implemented a method for locating landmarks in 2D-images of faces. It uses the weighted correlation coefficient as a similarity measure between the template ...

The contingency table is one of the most popular ways of presenting categorical data. We can make a visualisation of data contained in the two - way contingency table using the vcd and graphics packages in the R sofware. ...

The problem of optimizing the estimation of the weights of p objects in n weighing operations using a chemical balance is considered. Conditions under which the existence of an optimum chemical balance weighing design for ...

The simplest version of minority game is introduced. It is shown how the minority game can result from the behaviour of individuals. The stability analysis of stationary state is briefly discussed. The modification of ...

The paper gives an attempt to systematize different problems in finance which can be solved by multivariate analysis. First of all, some theoretical remarks on multivariate distributions are given. Then, taxonomy of ...

The problem of the estimation of unknown weights of p objects is considered. The experiment is carry out according to the model of the chemical balance weighing design under the assumption that the measurement errors are ...

The Goldfeld-Quandt test for homoscedasticity in a classical linear regression appears to be biased. In the paper an unbiased test is constructed. The result is extended to families of distributions with scale parameter.

In this paper an approach appealing to a regression depth concept is applied to a robust detection of points (moments) of a regression coefficients change. The propositions are compared with propositions based on Schwarz ...

In the paper we analyze the accuracy of the empirical best linear unbiased predictor (EBLUP) of the domain total (see Royall, 1976) assuming a special case of the general linear mixed model. To estimate the mean square ...

The author presents a synthetic overview of recent efforts related to the small area estimation methods applied to the Polish Labor Force Survey (PLFS). The review concerns methodology and results obtained by Central ...
