      Korzeniewski, Jerzy (Wydawnictwo Uniwersytetu Łódzkiego, 2000)
      In 1996 Zhang introduced sample replacement points for the level and power of tests and their simplified versions. This paper presents numerical values of the breakdown points of the Wilcoxon and sign tests for location ...

    • Multivalued Stop-Loss Stochastic Dominance Test 

      Trzpiot, Grażyna (Wydawnictwo Uniwersytetu Łódzkiego, 2000)
      Stochastic Dominance tests can be employed to assist decision-makers in ordering uncertain alternatives. Thes tests require specification of alternatives probability distributions and the assumption of the utility function ...

    • Estimation of Mode on the Basis of a Truncated Sample 

      Wywiał, Janusz (Wydawnictwo Uniwersytetu Łódzkiego, 2000)
      The problem of estimation of the mode of a continuous distribution (unction is considered. The estimation of the mode based on estimators of the density function is well known, see e.g. Härdle (1991) and Parzen (1962). ...

    • Logical Many-Valuedness Versus Probability 

      Malinowski, Grzegorz (Wydawnictwo Uniwersytetu Łódzkiego, 2000)
      The aim of the papers is to present and discuss the most direct issues on relation between logical many-valuedness and logical probability i.e. probability related to propositions. Having introduced the reader into the ...

    • Evaluation of the Probability Content as an Infinite Linear Combination of Wishart Distributions 

      Jelenkowska, Helena T. (Wydawnictwo Uniwersytetu Łódzkiego, 2000)
      The distribution function of the homogeneous generalized quadratic form is represented as an infinite linear combination of the central Wishart distribution functions. The Probability content of the ellipsoid is expressed ...
