Optimality of Spring Balance Weighing Designs
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
In this paper, the problem of existence of optimal spring balance weighing designs
is discussed. Two optimality criterions are compared and the appropriate optimality conditions are
presented.
Testing Differences between Populations with Eigenvectors
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
Testing differences between multivariate populations is one of a crucial problems
in statistical investigations. The most known – MANOVA tests being parametric ones need to
fulfill the assumptions about the conformity ...
Classification of Large Data Sets. Comparison of Performance of Chosen Algorithms
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
Researchers analyzing large (> 100,000 objects) data sets with the methods of

Bayesian Statistical Tests for Proportion for Independent and Dependent Sampling
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
As a result of the use of the Bayesian statistical tests, the decision of the acceptance
of the hypothesis for which the posterior risk is lower, is made. The risk depends on the prior
parameter’s distribution, the loss ...
