    • Numerical Aspects of Determining Measures and Contours in Depth for Data in R2 

      Kobylińsk, Małgorzata; Wagner, Wiesław (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      Measures and contours in depth are new statistical techniques applied in the analysis of observations. They are particularly applied in the visualisation of 2-dimentional samples in R2 space. The theory of measures and ...
    • Wielokrotna testowa procedura krocząca w analizie regresji 

      Parys, Dariusz (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      The multiple procedure for stepwise regression analysis presented in this paper is based on traditional methods, such as F-lest and test of partial correlations. This procedure, having multiple testing character, keeps the ...
    • Multivariate Multivalued Random Variable 

      Trzpiot, Grażyna (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      Given a probability measure space (Ω, A, P), random variable in classical definition is a mapping from Ω to R. Multivalued random variable is a mapping from Ω to all subset of X. For a real separable Banach space X with ...
    • Relations Between Chemical Balance Weighing Designs for p=v and p=v+1 Objects 

      Ceranka, Bronisław; Graczyk, Małgorzata (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      The incidence matrices of ternary balanced block designs for v treatments have been used to construct chemical balance weighing designs for p = v and p = v + 1 objects with uncorrelated estimators of weights. Conditions ...
    • Moc testów losowości opartych na liczbie serii wielokrotnych 

      Domański, Czesław (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      Tests based on the number and length of runs find their use more and more often. The reason is that they are nonparametric tests i.e. the ones that need no assumptions on the population distribution. Some of these tests ...
    • Estimation of Measurement Error Using Local Sampling and Joint Nonparametric Linearisation 

      Górkiewicz, Maciej (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      This paper presents how to use the near neighbours technique in aim to transform a given data set (Z, X, YT) of size N into a set of J ~ N local samples (Z, X), with restrictions on minimal number К of members in each local ...
    • Ilorazowe testy sekwencyjne dla frakcji dla prób nieprostych 

      Pekasiewicz, Dorota (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      Sequential probability ratio tests may be used to verify statistical hypotheses not only when sample is drawn sequentially independently but also when the sampling is performed according to other patterns. In the paper a ...
    • Losowa fluktuacja wyników wyceny planów emerytalnych. 

      Gajek, Lesław (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      In the paper the statistical fluctuation of the results of pension plan valuation (by use of unit credit method) is estimated. It is shown that the variance of the relative deviation of the valuation result from the proper ...
    • Time Dominance in Classification of Dynamic Structure 

      Kaczanowicz, Małgorzata (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      The idea of time dominance was formulated about twenty years ago and this term means the greater utility value of one „fact" over the other in every moment of strictly defined period of time. The dominance ranking methods ...
    • Some Practical Problems of Multivariate Survival Analysis of Epidemiological Studies 

      Jasiński, Bogdan; Kawalec, Ewa; Kupść, Witold (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      In the epidemiological analysis of chronic diseases (most often cardiovascular or cancer) the main problem of interest is the estimation of the risk of death (or getting ill) related to set of characteristics called risk ...

      Pasewicz, Wiesław; Wagner, Wiesław (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      Probability model on match involving two opposing players is discussed with particular emphasis on the relative probabity of a server in a play. It is assumed that player A has a constant probability pA of winning any point ...

      Domański, Czesław; Korzeniewski, Jerzy ORCID (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
    • Methods of Two Dimensional Images Restoration 

      Korzeniewski, Jerzy ORCID (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      In the paper the problems of segmentation and restoration of two dimensional images on the basis of possessed distorted version of images are considered. Bayesian methods of image analysis, ICM Besag algorithm, mathematical ...
    • On the Backward Selection Procedure for Graphical Log-linear Models - Monte Carlo Results 

      Rossa, Agnieszka ORCID (Wydawnictwo Uniwersytetu Łódzkiego, 2002)
      The analysis of categorical data by means of log-linear models is one of the most useful statistical tools available, particularly in the social and medical sciences, thus in all the sciences where we deal with collection ...
