Model Selection Methods in Log-Linear Analysis
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)The main objective of the study is to examine model selection methods in loglinear analysis. Log-linear analysis is a tool for independence analysis of qualitative data. Cell counts are Poisson distributed and all variables ... -
Modification of Talavera Method of Variable Selection in Cluster Analysis
Korzeniewski, Jerzy
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)
Talavera has proposed a method of variable selection in cluster analysis for data sets in which only variables measured on nominal scale are present. He examined the method on a couple of data sets basing his assessment ... -
On Model Selection in Some Regularized Linear Regression Methods
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)A dynamic development of various regularization formulas in linear models has been observed recently. Penalizing the values of coefficients affects decreasing of the variance (shrinking coefficients to zero) and feature ... -
On Parameter Estimation of Some Longitudinal Model
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)The problem of modeling longitudinal profiles is considered assuming that the population and elements’ affiliation to subpopulations may change in time. Some longitudinal model which is a special case of the general ... -
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. -
Properties of Transformation Quantile Regression Model
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)We present in this paper a few important direction on research using quantile regression. We start from some motivation for this method of regression. Secondly we present some main areas of application this method. Finally ... -

Some Construction of Factorial Designs
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)Design of experiments methods are an important tool to improve production processes using statistical methods. Designing experiments allows to set factors of the production process as well as describe the influence of ... -
Some Remarks on the Data Imputation Using “missForest” Method
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)Missing data are quite common in practical applications of statistical methods and imputation is a general statistical method for the analysis of incomplete data sets. Stekhoven and Bühlmann (2012) proposed an iterative ... -
Some Remarks on the Symmetry Kernel Test
Baszczyńska, Aleksandra (Wydawnictwo Uniwersytetu Łódzkiego, 2013)
The paper presents chosen statistical tests used to verify the hypothesis of the symmetry of random variable’s distribution. Detailed analysis of the symmetry kernel test is made. The properties of the regarded symmetry ... -
Statistical Time Series Analysis of Macro Indicators of Educational, Professional and Family Careers of Women in Poland
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)Educational, professional and family careers can promote each other, but more often they compete with each other, especially in a case of women. These careers change over time. This article aims to analyze changes over ... -
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 ... -
The Application of the Tools of Spatial Statistics to Evaluation Regional Differentiation of Polish Agriculture
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)The article presents the application of the spatial autocorrelation analysis in evaluation of regional differentiation of agriculture in Poland. The study based on the selected data for the sixteen provinces from the ... -
The Influence of Choice of Methods of Checking on Total Quality Control Costs
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)Acceptance sampling is commonly used in factories, because it decreases the probability of giving defective batch to the customer. From two distinguished ways of acceptance sampling, more frequently in practice is used ... -
