Weighting in the template matching
(Wydawnictwo Uniwersytetu Łódzkiego, 2008)
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 ...
Visualisation of a two - way contingency table in R
(Wydawnictwo Uniwersytetu Łódzkiego, 2008)
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. ...
Optimal designs for 𝘱 + 1 objects based on designs for 𝘱 objects
(Wydawnictwo Uniwersytetu Łódzkiego, 2008)
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 market as the Minority Game and the statistical physics
(Wydawnictwo Uniwersytetu Łódzkiego, 2008)
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 ...
Multivariate distributions in financial data analysis - applications in portfolio approach
(Wydawnictwo Uniwersytetu Łódzkiego, 2008)
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 ...
Note on the optimum chemical balance weighing design for odd number of objects
(Wydawnictwo Uniwersytetu Łódzkiego, 2008)
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 ...
Goldfeld-Quandt test: unbiasedness vs symmetry
(Wydawnictwo Uniwersytetu Łódzkiego, 2008)
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.
About robust detection of a breakdown point in selected linear regression models
(Wydawnictwo Uniwersytetu Łódzkiego, 2008)
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 ...
On accuracy of some EBLU predictor
(Wydawnictwo Uniwersytetu Łódzkiego, 2008)
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 ...
Application of bayesian estimation methods for small domains in the Polish Labor Force Survey
(Wydawnictwo Uniwersytetu Łódzkiego, 2008)
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 ...
